Spacer Insulating Parts with 99% Alumina Ceramics for Electrical Insulation

The Al2O3 content of high-purity alumina ceramics is 99% or higher. Due to its high sintering temperature of 1600-1650 ° C, it can be used as an integrated circuit board and insulation material in the electronics industry. High purity alumina ceramics have low high-frequency dielectric loss and excellent insulation performance, and are used to prepare insulating devices, ceramic substrates, and transparent alumina ceramics.
