The backbone of the electronic ceramics industry-Barium titanate

Barium titanate is an inorganic material with the chemical formula BaTiO3, which is a strong dielectric compound material with high dielectric constant, low dielectric loss, large resistivity, high compressive strength and excellent insulating properties, etc. It is widely used in multilayer ceramic capacitors (MLCC), thermal sensitive resistors (PTCR), electro-optical devices and dynamic random memory ( FRAM), etc. It is the basic raw material of electronic functional ceramic devices, so it is called the pillar of electronic ceramics industry by the majority of scholars and manufacturers.

Structure

Barium titanate is a coherent molten compound with a melting point of 1618°C. It has five crystalline variants: barium titanate, barium titanate and barium titanate.
