Description of Sintered Mullite Brick
Sintered mullite bricks are a type of high-temperature refractory material known for their excellent thermal stability and resistance to thermal shock. They are primarily composed of mullite crystals, which are formed through a sintering process involving raw materials like alumina and silica.
 
Sintered mullite bricks are primarily composed of mullite, a crystalline material made up of alumina (Al₂O₃) and silica (SiO₂). The specific composition may vary depending on the manufacturer and the intended application.
 
Features of Sintered Mullite Brick
