Furnace Materials

Bubble alumina brick is a kind of light neutral heat preservation refractory material with super high temperature and energy saving. Alumina hollow ball bricks are not only small in body density, but can optimize the structure to reduce the weight of the furnace body, but also have low thermal conductivity, which has a good thermal insulation effect. It is mainly used as the lining of high-temperature industrial kilns below 1800°Cz such as petroleum, chemical, electronics, ceramics, refractory materials and other industries. It plays a pivotal role in various industries.

Corundum-mullite brick refers to a high-aluminum refractory product composed of corundum and mullite main crystal phases. Corundum-mullite bricks refer to refractory products made of high-purity or relatively pure raw materials.

Mullite insulation brick is a lightweight refractory brick, the main component of which is mullite (3Al₂O₃·2SiO₂), a mineral material with high refractoriness and low thermal conductivity.

Mullite insulation brick is usually used in the thermal insulation layer of industrial kilns and thermal equipment. Its main purpose is to provide a thermal insulation effect while reducing heat loss and improving the thermal efficiency of the equipment.
