Alumina porous (KR-98-VG)
KR-98-VG is a pure alumina grade which, thanks to its open pores of approx. 23%, is more resistant to temperature changes than a high-density grade. In the steel industry, it is used for melting alloys or special steels. This ceramic is also utilised, for example, for safety crucibles. Thick-walled components which have high-strength properties can be made from this material.
- high mechanical strength
- high corrosion resistance
- temperature resistance up to over 1750 °C
- good thermal insulation
- high electrical insulation capacity
- chemically resistant to copper, chromium, bismuth, manganese, iron, etc.
