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:China Cup ceramic cup and what's the difference?
The difference between Bone China and porcelain ceramics []:1, the severity of bone and bone allograft: comparison of ceramic type will be very light;2, color: China color jade jade, ceramics will pan green color3, good light permeability: China4, excellent insulation: compared with the traditional porcelain, Bone China and better insulation, drink coffee or tea has a better taste;5, more durable: because bone porcelain and porcelain of the different ingredients, can be thinner and more durable, not easy to wear and tear, bone at 180 C and 20 C water heat exchange of a crack;6, high grade Bone China is currently the only recognized species of high-grade porcelain, double the value of both use and art, is a symbol of power and status, known as the king of porcelain, Bone China on the screen to do will seem very real, very clear7, listen to the voice of the bone in hand heart, take a pen or a small stick on bone bowl will issue such as bell like sound;8, choose a large porcelain bowl, pour about finger joint first day so much water, water around the finger bowl rub, this makes a resonance like "squeak" sound.
Q:What is the ceramic material?
General ceramic raw materials with high hardness, but poor plasticity. In addition to the use of food, decoration, also plays an important role in the development of science and technology. Ceramic raw material is the vast resources of clay, the original quartz and feldspar after processing.
Q:Which is better, Bally ceramic or specially made ceramic?
See how many meters in your pocket, specially positioned high-end brand of ceramics, the price of natural not so close to the people, Kim is a generic consumer brands, cost-effective, more affordable. To be honest, as long as it is Guangdong brick, almost the same national standards.
Q:Ceramic full glaze hanging process
The other one is not in the drilling mud, glaze by refractory support glaze glaze firing process to complete. The former is often used in small or light weight products, and the latter is used for bulky or bulky products
Q:Want to use piezoelectric ceramics to produce ultrasonic,
1, the human ear can feel the sound frequency range is 20Hz-20kHz, ultrasonic exceeds this frequency, even if the ultrasonic wave, you also can not hear
Q:Are ceramic knives expensive? What's the quality? What brand can you recommend?
Your price is certain, but the quality is hard to say
Q:The difference between ceramic, enamel, porcelain?
Two characteristics of china:1, the appearance of the United States: Porcelain delicate and transparent, elegant and elegant style, the color of the surface is smooth and bright, colorful flowers2 high grade: produced in the UK, has long been a special porcelain of the Royal and noble, is currently the only recognized species of high-grade porcelain, double the value of both use and art, is a symbol of power and status, known as the king of porcelain.Guzhici after high-temperature biscuiting and low temperature glaze firing two times, as high whiteness, good transparency, delicate porcelain, glazed smooth and bright porcelain, known as "paper thin, white jade, bright as a mirror, such as chime sound" reputation. Bone china tableware not only has a colorful appearance, but also has the quality of safeguarding people's health. Bone china is a traditional ceramic raw material added with animal bone powder after firing, the fetus is thin and bright, and has greater toughness. Guzhici endorsement of green ceramic glaze, Bone China is to screen in high temperature melting lit glaze, and the picture is not easy to wear, do not fall off, can be called "health ceramics fully deserve".
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 are the differences between antistatic ceramics and conductive ceramics?
Some ceramic oxide conductive ceramic is heated, electrons in atomic layer can obtain enough energy to overcome the nucleus of its appeal, and become a free electron movement, the ceramic becomes conductive ceramics.
Q:Is the floor wood good or ceramic good?
Maintenance: now the composite floor, basically do not need special care. Just use a mop when you're a little dry. Don't drip. Floor and tile compared to a lot of people know the misunderstanding: ordinary people believe that tiles are not easy to dirty, dirty things will not seep into, and the floor will seep into, not rub down. In fact, on the contrary, the surface of the floor is a wear-resistant layer, is never water seepage. Environmental protection: the main pollutants in the floor are formaldehyde. And ceramic tile main harm is radioactivity, invisible, unfavorable to differentiate. Space problem: the floor only takes up 1-1.5cm height, while tile takes at least 3-5cm height. The floor only lays a mat on the ground to cushion and prevent moisture, while the tiles need to be paved with at least three millimeters of sand dust. The above difference about wooden floor and ceramic tile floor, I have finished, and when buying the floor, I can choose what kind of floor suitable for myself according to what I say.
