Product Description


Zirconia is an extremely refractory material. It offers chemical and corrosion inertness to temperatures well above the melting point of alumina. The material has low thermal conductivity. It is electrically conductive above 600° C and is used in oxygen sensor cells and as the susceptor (heater) in high temperature induction furnaces. With the attachment of platinum leads, nernst glowers used in spectrometers can be made as a light emitting filament which operates in air.

Q:Now there are alumina ceramic knives on the market. What is the difference between this and the zirconia ceramic knives?
Zirconium in the ceramics of the best, rather cast iron parts, the ground will not be broken, alumina can not do, good or bad in a meter height drop, can be seen true and false
Q:The difference between China and the big ceramic
China is the only porcelain world invented by the west, was given a high evaluation value. In fact, China's emergence is purely accidental, strictly speaking, is not a very successful imitation and get unexpected results. "Cambridge history" of China China invention is described: the ancient China ceramic has high value in the west, its export history, even can be traced back to two thousand years ago. In Europe, the work of imitation ceramics has never been interrupted, but the real breakthrough is due to the development of Venice's glass industry. Today, it is known that the ceramic is made up of three parts: the enamel layer, the binding layer and the inner clay layer. One of the hardest to copy is the enamel layer. In fifteenth Century, the Venice people invented lead glass, and since then, a lot of experiments have been carried out in this field. It is found that the enamel layer of ceramics is similar to that of glass. Around seventeenth Century, Chinese Jingdezhen porcelain was introduced to Europe, this is a shocking invention, "Tao" China history said: "this kind of porcelain as thin as paper, white jade, bright as a mirror, such as chime sound". The European rule is: "thinner than paper, whiter than milk, and more glass than glass.". Brand can choose Germany only treasure brand, very good.
Q:As long as the ceramic containers can be put into the microwave oven?
Yes, as long as they are ceramic containers, they can be heated in a microwave oven.
Q:Why does glaze make ceramic surface smooth?
Ancient or made, oil, rust, also known as oil, glaze, glaze, medicine, etc.. Glaze is a silicate, applied on ceramics glaze with quartz, feldspar and clay as raw material, after grinding, adding water, coating on the surface of the blank body, the temperature of the roasting and melting, when the temperature falls, the formation of thin glass ceramic surface. It enables the ceramic to increase mechanical strength, thermal stability, dielectric strength, and to prevent the erosion of liquids and gases. The glaze also increases the beauty of the porcelain and is easy to clean and not stained by dust. Many kinds of glaze, according to material composition can be divided into lime glaze, glaze, glaze, feldspar lead and boron lead-free glaze glaze, glaze, glaze of lead boron salt; according to the preparation methods can be divided into raw glaze, glaze; according to the sintering temperature can be divided into high temperature, low temperature glaze glaze; according to the appearance features can be divided into transparent glaze, glaze, color glaze, crystalline glaze, color glaze, glaze crack; body according to the species can be divided into porcelain glaze, glaze pottery, stoneware glaze etc.. There are mainly two kinds of feldspar glaze and lime glaze in China's ceramic production. Due to the oxidation of metal contained in glaze and different sintering atmosphere different, glaze with blue, black, green, yellow, red, blue and purple. The ancient white porcelain was almost colorless transparent glaze.
Q:How can the ceramic tableware distinguish 28 heads and 56 heads?
In nature, there are not many sources of calcium oxide, so bone dust from animals is chosen as the source of calcium oxide.China is a unique nature of natural bone powder milk white. Generally speaking, raw materials containing 25% bone porcelain can be called bone china, the internationally recognized bone content than 40%, best quality Bone China contains 51% of the best bone powder. The bone component is more than 40%, appliance color is more white, high-grade bone porcelain. Only a small number of factories in Tangshan, Zibo and other places produce export products.After the grouting, molding, embryo, plaster mold dehydration, as well as the initial burning, glaze burning, decal baking process, high temperature firing, to become high whiteness, high transparency, porcelain delicate porcelain. Bone China in the firing process, its regularity, whiteness, transparency, thermal stability and other physical and chemical indicators are demanding, resulting in a high rate of waste.
Q:Brief introduction of honeycomb ceramics
Honeycomb ceramics can be made from a variety of materials. The main materials are: cordierite, mullite, aluminum titanate, activated carbon, silicon carbide, activated alumina, zirconium oxide, silicon nitride and cordierite, mullite, cordierite, aluminum titanate and other composite matrix. Activated carbon powder or granules made of ceramic honeycomb shape, greatly improve the treatment of water purification and wastewater treatment ability, especially in the pharmaceutical industry, antibiotics, vitamins, hormones and nucleic acid injection of various drugs such as injection, dehydration and decolorization to impurities etc.. Honeycomb ceramic can be divided into four categories: regenerator, filler, catalyst carrier and filter material. Ceramic honeycomb regenerative body heat capacity above 1000kJ/kg products, the highest use temperature more than 1700 DEG C, in heating furnace, heating device, soaking furnace, cracking furnace kiln fuel can be saved more than 40%, the yield increased by more than 15%, the temperature of exhaust gas is lower than 150 DEG C. Honeycomb ceramic filler filler than other shapes of greater surface area, better strength and other advantages, can make the vapor-liquid distribution more uniform, the bed resistance is reduced, the effect is better, and can prolong the service life, in the petrochemical, pharmaceutical and fine chemical industry as a filler effect is quite good.
Q:According to the difference of water absorption and sintering degree, which three kinds of pottery ware are divided into?
2, stoneware. Also known as semi porcelain, which is the main raw material of clay or clay. It is compact, fully sintered, but not fully vitrified, and basically does not absorb water. According to the texture is divided into coarse and fine stoneware stoneware two, commonly used in pottery jars, pottery etc..
Q:Principle of reducing burning point of ceramics by cosolvent
In addition, common fluxes are boric acid, borax and other boron oxides, and lead oxides, of course. Boron has a strong fluxing effect with lead.
Q:What sticks to ceramics?
1, ceramic and plastic bonding. For example: JL-100 bingxisuan ab. Green and red for various metals homogeneous or heterogeneous adhesive, and magnet, ceramic, stone, hard wood, PVC, FRP etc.. The impact resistance of metal articles is better than that of epoxy resin. Excellent heat resistance, placed at 150 DEG C for one week, still at normal temperature, weak in strength. Vibration resistance strength of iron: iron, 1000 times per minute vibration, vibration resistance 106, under UV light for 200 hours is not decreased strength.The other 2, adhesive bonding ceramic: for example: cohesion JL-510 high temperature of 200 DEG C resistant epoxy resin adhesive, JL-611 epoxy resin adhesive, 1 hours JL-610AB10 minutes drying transparent ab etc.. They also have excellent bonding strength for metal, ceramic, wood, glass and hard plastic packaging.
Q:What glue sticks to ceramics and plastics? Ten
Ceramic and plastic bonding can use 801 glue; 801 glue is a chloroprene phenolic strong adhesive, suitable for a wide range of bonding, bonding degree firm, but the price is higher. Low prices are fake and shoddy products, do not buy.
