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

Calcium oxide has a melting point of 2570°C, abundant resources and relatively cheap price, but it is difficult to sinter, has low stability in the atmosphere, and is easy to hydrate, which is the biggest problem in the manufacture of CaO products. The raw material used to prepare pure calcium oxide is chemically pure calcium carbonate or calcium hydroxide, which is burned at a temperature slightly higher than its decomposition temperature. In the process of manufacturing calcium oxide products, from the preparation of agglomerates to the firing of the products until they are used, they must be stored in a moisture-free medium. The hydration rate of calcium oxide in the Read more

Alumina ceramics have excellent insulation, low high-frequency loss but good high-frequency insulation, so what are the properties that alumina ceramics will improve after machining? Next, Pintejin ceramics will introduce to you. 1. Improve hardness The Rockwell hardness is up to the standard. Taking the processed wear-resistant ceramic patch as an example, its hardness is second only to that of diamond. It was found after many experimental verifications by alumina ceramic manufacturers. Physically speaking, after the alumina wear-resistant ceramic patch is processed, its hardness far exceeds the wear resistance of stainless steel and wear-resistant steel. It can be seen that its hardness is significantly improved after machining. 2. The wear resistance Read more

Pintejin Ceramics Factory is a professional manufacturer of precision ceramics machining, which can provide customized precision ceramics machining and production according to drawings. Below, Pintejin Ceramics Factory will introduce the sintering technology of precision ceramics to us. Precision ceramic nozzle The sintering technology of precision ceramics mainly includes the following methods: Atmospheric pressure sintering of precision ceramics, also known as pressureless sintering. It belongs to the process of free sintering of the green body under atmospheric pressure. In the absence of external power, the sintering temperature of the material generally reaches the melting point of the material at 0.5-0.8. Solid-phase sintering at this temperature can induce sufficient atomic diffusion in Read more

Although the zirconia ceramics we are familiar with have excellent performance and high hardness, it will inevitably require very precise machining during machining. Next, the Pintejin ceramics manufacturer will introduce to you the finishing methods and attention of zirconia ceramics. point. Finished zirconia ceramic tube Processing method of precision zirconia ceramic machining: Zirconia ceramic machining methods are commonly divided into two categories: mechanical machining, mold injection machining, etc. Among them, the mechanical machining method is highly efficient, so it is widely used in industry. Applications, especially diamond wheel grinding, lapping and polishing are common. Precautions for machining precision zirconia ceramic parts: Although there are many methods for machining precision zirconia Read more

Alumina ceramics are made by using alumina as the main raw material, adding 6-30% of clay, magnesium oxide, calcium oxide, titanium oxide and other sintering accelerators, and sintering at 1450-1800 ℃ after mixing. The more alumina content, the better the inherent properties of alumina can be exerted, and the better the performance, but it becomes difficult to manufacture as the alumina content increases. The characteristics of alumina porcelain are that it still has good insulating properties at high temperature. Pure alumina porcelain can be used at a temperature of 800 ° C. Its mechanical strength is the highest among all oxide ceramics, and its thermal conductivity is large and thermal Read more
