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.

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

Q:Why do tableware usually use ceramics?
Use:1. ceramics for daily use: such as tableware, tea set, jar, altar and basin. Pots, etc..2. art ceramics: vases, sculptures, furnishings, etc..3. industrial ceramics: ceramics used in a variety of industries. It is divided into the following 6 aspects:(1) building a sanitary ceramic: such as brick, drain pipe, brick, wall tile, sanitary and so on;(2) chemical ceramics: acid resistant containers, pipes, towers, pumps, valves, and acid bricks, ash, etc. used in lining reactors;(3) chemical porcelain: Porcelain crucibles, evaporating dishes, burning boats, grinding bodies, etc. used in chemical laboratories;(4) electric porcelain: insulator used for high and low voltage transmission line of electric power industry. Bushings for motors, insulation for insulators, insulators for low-voltage appliances and lighting, insulators for telecommunications, insulators for radios, etc.;(5) refractory materials: refractory materials used in various high-temperature industrial kilns;(6): special ceramic, special ceramic products thrown in various modern industry and advanced science and technology, high alumina ceramic, porcelain, stone magnesium titanium magnesium porcelain stone, zircon porcelain, porcelain, and lithium ferrite, metal ceramic etc..
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 Jingdezhen Ceramic Institute and Jingdezhen ceramic university?
Jingdezhen college was formerly a junior high school! Later, the college was upgraded! Tao courtyard 58 years, is the second batch of undergraduate!
Q:What kinds of ceramics do you have?
According to whether the glaze is divided, it can be divided into two categories: glazed ceramics and unglazed ceramics.The people in the production, research and Study on the convenience, and sometimes not according to the chemical composition, and according to the performance of ceramics, divided them into high strength ceramic, ferroelectric ceramic, acid resistant ceramics, high temperature ceramics, piezoelectric ceramics, high toughness ceramics, ceramic electrolyte, optical ceramics (i.e. transparent ceramics), magnetic ceramics, dielectric ceramics, magnetic ceramics and so on.It can be divided into three categories: hard porcelain, soft porcelain and special porcelain.The porcelain produced in our country is mainly made of hard porcelain. Hard porcelain body composition, flux amount, high firing temperature, at 1360 DEG C to Zhijian color white, translucent, good strength, high chemical stability and thermal stability, and is a poor conductor of electricity, such as porcelain tableware, senior porcelain, chemical porcelain, porcelain and other ordinary day is this kind, also called feldspar glaze.
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:Can the ceramic dish be baked in the oven?
All ceramic, should be no problem, ceramic bowl I baked a few times, all nothing, also, dishes are too big difference?
Q:The ceramic vase is broken. What can stick it up?
Garlic juice, mending, bonding, and so on. This glue porcelain is not only strong, and not to hurt the glaze, does not affect the appearance, not just water.From three to five cloves of fresh garlic, preferably purple garlic in peeled, mashed, put in the bowl, grinding, don't leave a lump, as Daocheng garlic juice.Take the clean gauze and remove the scum, leaving only the garlic juice. Take a fresh egg and make a small hole. Slowly let the egg whites out and mix it with the garlic juice.
Q:How is the quality of ceramics assessed?
Quality assessment requires a standard, which involves many aspects of construction ceramics. Mainly to see your use, general construction ceramics are imitation of natural stone. So compare the physical parameters of the natural stone you want to imitate with the building ceramics you need. The physical parameters of the natural stone are better than those of the natural stone. General physical parameters such as hardness, wear resistance, weather resistance, gloss, water absorption, acid resistance, alkali resistance, etc...
Q:Is electric clippers or ceramic knives good or alloy knives?
The ceramic cutter of the electric shear is better.Because of the hardness of steel is Vivtorinox HV700, ceramic knife hardness is HV1100, the higher the hardness of sharp.
Q:Why do ceramic knives cut onions without hot eyes?
This substance can stimulate corneal nerve endings, the human body through the nervous system the command of lacrimal gland tear secretion, the irritating substances washed away.Cut the onion with a ceramic knife. Because the ceramic knife is very sharp, it can not destroy the food tissue and make the irritating gas less volatile
