99 alumina ceramic parts
Normal typeAlumina ceramicsare divided into 99 porcelain and 95 porcelain according to the alumina content. Porcelain, 90 porcelain, 85 porcelain and other varieties, sometimes those with an Al2O3 content of 80% or 75% are also classified as ordinary alumina ceramic series. Among them, alumina 99 porcelain is used to make high-temperature crucibles, refractory furnace tubes and special wear-resistant materials, such as ceramic bearings, ceramic seals and water valves; 95 alumina porcelain is mainly used for corrosion-resistant and wear-resistant parts; 85 porcelain Because some talc is often incorporated into it, the electrical properties and mechanical strength are improved. It can be sealed with molybdenum, niobium, tantalum and other metals, and some are used as electronic vacuum device components.
Alumina 99 porcelain has good conductivity, mechanical strength and high temperature resistance. However, it should be noted that alumina 99 porcelain needs to be cleaned with ultrasonic waves.
Alumina 99 porcelain is a widely used ceramic. Because of its superior properties, its application in modern society has become more and more extensive, satisfying daily use and special properties. needs. It is widely used in working conditions with high cleanliness, high temperature and high wear-resistant environmental requirements.
Many people may confuse corundum and alumina 99 porcelain, so let’s teach you how to distinguish them.
Corundum, its name originates from India, is a mineralogy name, and its main component is Al2O3.
There are three main variants of homogeneous anomalies of corundum Al2O3, namely α-Al2O3, β-Al2O3, and γ-Al2O3. Corundum is second only to diamond in hardness and is mainly used for grinding materials. Bearing materials for watches and precision machinery, colorful crystals as gemstones, and ruby-based artificial crystals as laser emitting materials.
Ruby and sapphire are both corundum minerals. In addition to the starlight effect, only translucent-transparent and brightly colored corundum can be used as gemstones. The red ones are called rubies, while the other shades of corundum are commercially known as sapphires.
