  • Description
  • Sintered mullite bricks are made from sintered mullite, electric fused alumina, electric fused mullite, and special additives, formed under high pressure and sintered at high temperatures. They are mainly used in the upper part of glass furnace regenerator chambers, small furnace walls, arch tops, melting pool tops, and feeding channels. They feature high temperature resistance, good thermal shock stability, and low thermal expansion at high temperatures.
