Introduction to the application of this material by alumina ceramic manufacturers

Alumina ceramic is a newly discovered ceramic material in the modern industrial industry, which can replace existing metals and improve the performance characteristics of equipment. Today, we will introduce the advantages of this ceramic material.

Alumina ceramics have attracted much attention due to their unique color tone. In fact, what attracts many customers is not only its color tone, but also its various characteristics. Moreover, the manipulation of environmental pollution and the filtering of molten metal materials have long been a possibility.

Alumina ceramics have become a widely used and cost-effective new type of porcelain due to their diverse raw material mineral resources, high melting point, dielectric strength, and other functions. Because pure Al2O3 has a high melting point, few residues, and is very rare at high temperatures, it is necessary to use crushing and grinding of the raw material during basic calcination to increase lattice defects, activate grains, and add additives to form a low co solubility finite solid phase with the main crystal phase or form a grain boundary glass phase to achieve the purpose of sintering.

Type alumina ceramics are classified into types such as 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain, etc. based on different Al2O3 compositions. Sometimes, products with Al2O3 compositions of 80% or 75% are also classified as general alumina ceramic series products. Among them, 99% aluminum oxide ceramic raw materials are used to make high-temperature tongs, fireproof furnace bodies, and unique wear-resistant materials such as ceramic bearings, ceramic seals, and water valve plates.

95 alumina porcelain is mainly used as corrosion-resistant and wear-resistant parts. 85 porcelain is often mixed with some talc, which improves its electrical properties and mechanical strength. It can be sealed with metals such as molybdenum, niobium, tantalum, etc. Some are used as electric vacuum devices.

The strength of alumina ceramics is very high, both polycrystalline alumina ceramics and polycrystalline silicon alumina ceramics have high stainless steel hardness characteristics. Due to the strength of the self-locking bracket in porcelain, it can achieve over nine times the strength of the stainless steel plate and its enamel. Therefore, when our incisors come into contact with the ceramic bracket, the enamel will be worn off in a short period of time.
