PRODUCT DESCRIPTION：YONAI B995 is high purity bubble alumina
Description:
YONAI Bubble Alumina B995 is produced by
fusing special high purity alumina. The melt is atomized with compressed air
which leads to the hollow spheres.
Bubble Alumina is hard but extremely friable with respect to its pressure
strength.
The melting point is approximately 2100ºC. Due to its hollow spheres it has a low bulk density and extremely low thermal conductivity. B995 is chemically inert.
Applications:
Due to the above noted properties B995 is used to form pores in high porosity abrasives and as a media to filtrate aggressive liquids or melts. It can also be used as a bed in the firing process of vitrified grinding wheels.
