RFQ
1.What is alumina ceramic used for?
Alumina is a very hard ceramic that is excellent at resisting abrasion and is ideal for wear-resistant inserts or products. It is commonly used as a high temperature electrical insulator, particularly the higher purity grades which offer better resistivity.
2.Is alumina ceramic safe to use?
Alumina ceramic, composed mainly of aluminum oxide (Al2O3), is widely regarded as safe for various applications due to its biocompatibility, thermal resistance, and electrical insulation properties. Used in medical implants and dental applications, it is well-tolerated by the body.
3.Why is alumina expensive?
It is expensive, largely because of the amount of electricity required in the extraction process. Aluminium ore is called bauxite close bauxiteA rock that can be used to make aluminium.. The bauxite is purified to produce aluminium oxide, a white powder from which aluminium can be extracted.
