Alumina insulator is a type of ceramic material that is used to separate electrical conductors in high-temperature and high-voltage applications. It has excellent electrical insulation properties along with high thermal conductivity, making it suitable for applications where heat dissipation is important. Alumina insulators are commonly used in electronics, power equipment, and industrial furnaces.

What is difference between calcined alumina and alumina hydrate?

Calcined alumina is produced by heating alumina hydrate to high temperatures, which removes the chemically bonded water and results in a more pure form of alumina. Alumina hydrate, on the other hand, contains chemically bonded water molecules and is typically used as a flame retardant or filler material due to its lower processing temperature and cost effectiveness.
