What kind of special oxide ceramics are divided into? How strong is its high temperature resistance? (picture)

Special alumina ceramics are a common ceramics in industry, with high temperature resistance and other characteristics. What are the main types of special alumina ceramics? How strong is its high temperature resistance? 

Special alumina ceramics itself is a ceramic material based on alumina (Al2O3) as its main body for thick film integrated circuits. Special alumina ceramics have good conduction, mechanical strength and high temperature resistance.

Special alumina ceramics are divided into high -purity and ordinary types. High -purity type refers to ceramic materials with an AL2O3 content of more than 99.9%. The general type refers to the different contents of AL2O3, which are divided into 99 alumina ceramics, 95 alumina ceramics, 90 alumina ceramics, 85 alumina ceramics and other varieties. Sometimes the AL2O3 content of 80%or 75%is also classified as ordinary aluminum ceramic series.

99 Amaxy alumina ceramics has good high temperature resistance. 99 alumina porcelain materials can be used to make high -temperature crickets, fire -resistant furnace pipes and special wear resistance materials, such as ceramic bearings, ceramic seals and water valve pieces.

Special alumina ceramics can reach up to 1700 ° C. Because special alumina ceramics are divided into two types, the high temperature resistance of ordinary 99 alumina ceramics is relatively prominent. 99 One alumina has a high melting point, high hardness and high mechanical strength. Due to the increase in relative thermal expansion coefficients, the stability of thermal shock is reduced. When you want to use high temperature resistance, 99 alumina ceramics are the best choice.

Because special alumina ceramics still have excellent insulation performance at a high temperature of 1000 ° C, it has been widely used in electronic appliances, military scientific research and other industries. In addition, alumina ceramics can also have abrasion resistance and high temperature resistance, so more and more industries have begun to use alumina ceramics materials to replace traditional plastic materials parts.

The above is the introduction of the species of alumina ceramics and high temperature resistance. We can process ceramic products according to your drawings, specializing in the production of high -precision ceramic sticks, ceramic tubes, ceramic rings, ceramic plunges, ceramic valves, ceramic nozzles, and customized ceramic parts.
