Lightweight Fire Brick Classifiion and Characteristics Lightweight fire brick, according to the raw materials used, can be divided into mullite, siliceous, aluminum and clay. Lightweight fire brick, also known as lightweight insulating firebrick, is due to the large nuer of pores (including closed and open pores) in the fire brick.. Lightweight insulating fire bricks have low compressive
Self-sintered silicon carbide carries a slight price premium compared to the reaction bonded version. Although the preferred seal face material, it often is too brittle for some seal face designs. It is one of the most popular materials used in mechanical seal face design and is recommended in high temperature water or hot oil appliions because of its excellent thermal conductivity.
