Product Description

Zirconia Ceramic 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.

Properties of High Pressure Zirconia Ceramic Nozzle


(1). Excellent in electrical insulation;
(2). High hardness and wear/corrosion resistance;
(3). High working temperature;
(4). Good thermal shock resistance;

Q:Ceramics with excellent products and first-class goods is how divided?
It is the best grade, no concept of honorsBut now the general order is the standard of agreement, so to speakIf you are both first-class and superior, superior is better than grade oneBut the general manufacturers will not be so out of order, inappropriateGenerally superior and qualified productsAt this time superior than first class goods, a little better than qualifiedSo one, two of the bar, qualified, basically three class appearance
Q:What is the difference between ceramic tile and ceramic tile?
The difference between ceramic tiles and ceramic tiles lies mainly in water absorption. Water absorption is generally less than 0.5% for tiles, more than 10% for pottery bricks, between the two half porcelain. Usually all kinds of polished tiles, glazed tile, sanitary ware, porcelain is the most general, bibulous rate is less than or equal to 0.5%; small antique brick, tile (the wall), crystal tiles, wear-resistant bricks, Yaguang brick is brick, half tiles, bibulous rate is 0.5% tiles, ceramic pipe, decorative tile, glass products the general is ceramic, the water absorption rate of >10%. This is the important difference between ceramic tile and ceramic tile
Q:The electric cooker can burn it in gas
Look at product quality. Generally yes, my own home is burned on the fire. If the pot is large, easy to heat, uneven rupture.
Q:Ceramic pot for a long time, how to clean the dirt?
Very simple, heating water soak overnight, second days just wash. No, just one more night.
Q:What is the difference between ceramic and enamel? Which is more harmless to the human body?
The ceramic clay raw material, barren material and raw material flux through proper proportioning, crushing, molding and high temperature roasting in the case after a series of physical and chemical reaction, the formation of hard materials. More common are: ceramic tea sets, ceramic plates, ceramic bowls, a variety of ceramic living utensils. Multi expression ceramic multifunctional seasoning pot is coated on the metal surface enamel layer or several layers of enamel, by firing a composite material, both physical and chemical reactions and solid combination. The greatest benefit of this is corrosion resistance. Relatively common, such as: enamel pan, enamel, washbasin, etc..
Q:What's the inner core in the shower? Some people say that all copper is good, some people say that the ceramic core is good.
1, it is recommended to use ceramic core.Have the advantages of the 2, the two, copper core capable of sterilization, in the aspect of environmental protection is a good choice, ceramic core strong corrosion resistance, no matter how important is bought is real, because now there are many businesses in the pursuit of higher profits, cut corners on the market, resulting in product quality is no, especially in copper, if mixed with some impurities, it is easy to form the primary cells, produce the redox reaction, is a great harm to the human body.
Q:What is the difference between ceramics?
The difference between pottery and porcelain:Pottery appeared earlier than porcelain. There were pottery in the primitive stone age. Porcelain did not appear until the end of the northern and Southern DynastiesTao is not (except pottery) and uranium when burning temperature is not high porcelain, material is a kind of clay, porcelain to uranium, material may be a mixture of soil and minerals; produce different colors by the mineral elements in the Tao; only 3 colors: red; 100; determined by black. Soil color.The main raw material of China is mud; the color is mostly white or yellow; and the finished product is determined by uraniumBesides, the hardness of pottery is inferior to that of porcelain; but porcelain is not as good as earthenware;
Q:What material does the ceramic brake pad make of?
Ceramic brake pads are a kind of brake pads, not made of ceramics. In fact, the main components of ceramic brake pads are mineral fiber, aramid fiber and ceramic fiber.The ceramic brake pads are lighter and more expensive, cleaner and quieter than other brake pads, and wear dual parts while providing superior braking performance.
Q:Vary render ceramic parameters
Basic parameters: pottery, white, anti.254, hook, philippines,Porcelain: diffuse, white, anti.180-220, high gloss, 0.88 gloss, 0.9 hookCeramic: diffuse, white, anti.160, high light, 0.75 hooksSingle parameter is useless, you have to understand the meaning of it, after the figure of material without texture, not only material problems, lighting effects are also great
Q:What kind of equipment do you need to open a ceramic factory?
First of all to have a small pit furnace (electricity, gas, coal and oil) can be. Another ball mill and several sets of product molding equipment and production equipment, but also have some mold and all kinds of raw material and site. The preliminary estimate to one million yuan to start production, but also of course this is engineer in order to do. Now the pit furnace equipment is very expensive. A stove I (gas) only twenty meters long spent nine hundred and fifty thousand yuan.
