Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
Alumina ceramics are known as corundum, and the name is derived from India and is a mineralogical name. There are three main variants of corundum Al2O3, which are α-Al2O3, β-Al2O3 and γ-Al2O3. Corundum hardness is second only to diamond. Corundum is mainly used for bearing materials for advanced abrasive materials, watches and precision machinery. A ruby-based artificial crystal as a laser emitting material. Both rubies and sapphires belong to corundum minerals. Except for the starlight effect, only translucent-transparent and colorful corundum can be used as gemstones. Red is called ruby, while other shades of corundum are collectively called sapphire. The name Corundum is derived from India and is a mineralogical name. Ruby and sapphire are known as gemstones. Myanmar, Sri Lanka, Thailand, Vietnam and Cambodia are the world's most important suppliers of quality rubies and sapphires. Other producing countries include China, Australia, the United States, and Tanzania.
Wear resistant
Abrasion-resistant materials are a large class of new materials with special electrical, magnetic, optical, acoustic, thermal, mechanical, chemical and biological functions. They are important basic materials for high-tech fields such as information technology, biotechnology and energy technology, and national defense construction. At the same time, it also plays an important role in transforming some traditional industries, such as agriculture, chemicals, and building materials.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
