Alumina Insulating Ceramics Can Be Customized With Alumina Accessories
Alumina ceramics have many excellent properties, so they are widely
used in the world. Alumina ceramics have a Vickers hardness of
15GPa, a density of about 3.75g/cm3, a compressive strength of
about 2100MPa, a flexural strength of 300Mpa, a volume resistance
of 1014Ω·m, an expansion coefficient similar to that of metals, and
good chemical stability.
