Lightweight Mullite Corundum Brick
Feb 05, 2018

Basic Info

Product Description

  • Refractoriness (℃): 1770< Refractoriness< 2000

  • Type: Refractory Material

  • Material: Mullite

  • Feature: Long Time Materials

  • Shape: Brick

Lightweight mullite corundum brick is made after molding and high temperature sintering by mixed the white corundum, fused mullite and burning agent. With features of high temperature resistance, low thermal conductivity (good heat insulation effect, can make the pit wall thinner and reduced cost), high strength, high temperature stability etc. It is widely used in all kinds of high temperature furnace lining and insulation layer. http://www.slazs.com
