Types of JM32 Insulation Fire Brick
| Types | Production | Features |
| Sintered Type | The primary raw material for sintered mullite insulating bricks is high-alumina bauxite, with small amounts of clay or raw alumina as a binder. It is formed and then sintered. | Mullite crystals; Relatively loose structure; Good thermal shock resistance; Good slag resistance; |
| Fused Type | Fused mullite bricks are made from high-alumina bauxite, industrial alumina, and refractory clay. Charcoal or coke fines are added as reducing agents. After shaping, they are produced using a reduction melting process. | Larger crystals; Compact structure; Better thermal shock resistance; Better slag resistance. |
