High temperature resistant ceramic parts are widely used in various fields of our country’s national economy and people’s livelihood. So what are the high temperature resistant ceramic parts and what are they used for? Pintejin zirconia ceramic machining manufacturers answer for you. High temperature resistant ceramics is a general term for ceramic materials whose melting temperature is above the melting point of silicon oxide (1728°C). High temperature ceramic cutter is an important part of special ceramics, and sometimes also used as a component of high temperature refractory materials. According to the main chemical composition of the material, it can be divided into high temperature oxide ceramics, such as zirconia ceramics Read more

Zirconia ceramic materials have many advantages and characteristics, so all kinds of products made of zirconia ceramics have good characteristics, and at the same time have been widely used, so what are the usesd zirconia ceramic materials? Come down and introduce Pintejin Ceramics to you. 1. The zirconia ceramic crucible made of zirconia ceramic material can successfully melt platinum, palladium, ruthenium, cesium and other precious metals and their alloys, and can also be used for the smelting of potassium, sodium, quartz glass, oxides and salts. 2. Zirconia refractory fiber of zirconia ceramic material is the only 1600c ultra-high ambient temperature that uses ceramic fiber refractory material for a long time Read more

The zirconia ceramic products we know have very good toughness. They fall intact from a height of 1 meter, are very resistant to falling, and have very good wear resistance. They are very practical in various fields. Then such zirconia ceramic machining is How is it? Next, Pintejin Ceramics, a manufacturer specializing in the production of zirconia ceramics and alumina ceramics, will focus on the detailed process of zirconia ceramics machining. Zirconia ceramic ring Zirconia ceramic machining flow: The first step of zirconia ceramic machining: procurement of raw materials, that is, zirconia powder, zirconia powder is white heavy amorphous powder. Odorless. Tasteless. Soluble in a mixture of 2 parts of Read more

With the continuous development and progress of science and technology, alumina ceramics with superior performance are widely used in various fields due to their own advantages. We know that wear resistance is a very important performance feature of alumina ceramics. What will affect the oxidation resistance? What about the wear resistance of aluminum ceramics? The following is a brief introduction to the performance of alumina ceramics and the influencing factors of wear amount by Pintejin ceramic manufacturers. Alumina Ceramic Plunger Alumina ceramic has good high temperature resistance, high mechanical strength and good conductivity. However, it should be noted that when washing the ceramic, it should be washed with ultrasonic waves, Read more

At present, the main raw material for the production of special alumina products is industrial alumina, which is an intermediate product of the aluminum smelting industry. Its true density is 3.60g·cm-3, and its mineral composition is γ-Al2O3. Industrial alumina is white powdery material. The chemical composition of general products is shown in the table. When manufacturing special pure products, raw materials with Al2O3 content greater than 99.8% or raw materials prepared from aluminum sulfate and ammonium sulfate should be used. Industrial alumina is difficult to sinter. In order to improve the sintering temperature, the raw materials need to be finely pulverized and pre-sintered, and additives that promote sintering are added. Read more

What industries are ceramic parts generally used in? Our ceramic parts can be divided into ordinary ceramic parts and precision ceramic parts. In which industries are these ceramic parts generally used? Next, Pintejin Ceramics, a manufacturer specializing in the production of zirconia ceramics and alumina ceramics, will tell you which industries the key ceramic parts are generally used in. Alumina ceramic parts Which industries are ceramic parts generally used in: Ceramic parts mainly refer to those mainly used in chemical plants for filtration and purification, as well as for grinding materials. Building-sanitary ceramics: such as bricks and tiles, drainage pipes, face bricks, exterior wall tiles, sanitary ware, etc.; Chemical (chemical) Read more

In recent years, my country’s industrial ceramics have developed rapidly, and it has become a large cross-industry and interdisciplinary industry. The output value of the national industrial ceramics has accounted for more than half of the ceramic industry, and it has a very important strategic position in the entire national economy. Experts predict that the market demand for industrial ceramic products in China will grow at an average annual rate of about 8.5%. Industrial ceramic technology is an important part of the application field of science and technology. Most high-tech development is inseparable from high-tech industrial ceramics, and the development of high-tech industrial ceramics also requires high-tech support. Facing the Read more

The production of ceramic products has a long history in China. After a long period of development, the manufacturing process has been continuously developed. Especially in the past two decades, the reasonable adjustment of the structure of zirconia ceramic products has catered to the consumer demand of consumers at home and abroad, and with the development of society and the improvement of living standards, the application range in life has become wider and wider. At the same time, my country’s total export trade of ceramic products is making every effort to increase. The export of daily-use ceramics, architectural ceramics, sanitary ceramics and zirconia ceramics has shown a gratifying scene of Read more

The sintering temperature of zirconia ceramics is very high when the recrystallized silicon carbide setter is used for production. high; The working temperature of the recrystallized silicon carbide setter plate can reach 1650 ℃; the thermal shock resistance is excellent and the best setter plate; but because the main component of the silicon carbide setter plate is SIC+SIO2; Among them, the SIO2 in the recrystallized silicon carbide setter plate cannot be completely obtained from the group, so some SIO2 still exists in the form of crystalline; Due to the relatively high activity of SIO2, when SIO2 encounters all substances that can be combined at high temperature, it will immediately combine Read more

Appearance of activated alumina: activated alumina is white spherical porous particles with uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, no swelling or cracking after water absorption, non-toxic, odorless, insoluble in water and ethanol, It has strong adsorption to fluorine and is mainly used for defluorination of drinking water in high fluoride areas. Activated alumina has selective adsorption capacity for gas, water vapor and moisture in some liquids. After the adsorption is saturated, it can be heated at about 175-315 ° C to remove water and resurrected. Adsorption and resurrection can be performed multiple times. In addition to being used as a desiccant, it can also absorb the Read more
