calcium Mullite powder

Mullite bricks refer to high-alumina refractory materials with mullite as the main crystal phase. Generally, the alumina content is between 65% and 75%. In addition to mullite, the mineral composition contains a small amount of glass phase and cristobalite in those with lower alumina content; a small amount of corundum in those with higher alumina content. Mainly used in hot blast furnace tops, blast furnace shafts and bottoms, glass melting furnace regenerators, ceramic sintering kilns, dead-end furnace linings in petroleum cracking systems, etc.

A honeycomb ceramic regenerator is a type of heat exchange device used in certain combustion systems, such as industrial furnaces and heating equipment. It is designed to recover heat from flue gases and transfer it to the incoming combustion air, improving energy efficiency and reducing fuel consumption.

Baffle bricks are a type of refractory brick that are used in various industrial heating equipment, particularly in furnaces and kilns. They are typically installed as baffles or partitions within the equipment to control the flow and direction of heat, combustion gases, and materials being processed. Baffle bricks are designed to withstand high temperatures, thermal cycling, and chemical attacks. They are usually made from high-quality fireclay or high alumina materials, which provide good thermal insulation, high refractoriness, and resistance to abrasion and corrosion.

Lightweight mullite castable is a new type of material using porous mullite as aggregate. The aggregate is artificially synthesized at high temperature, with the main crystal phase reaching more than 70%, and its composition is uniform and stable. The binding agent is made of pure calcium aluminate cement or aluminate cement, mixed with mullite powder, alumina powder, silica powder, kyanite, etc.
