Light Brick


Lightweight clay bricks refer to lightweight refractory products with an aluminum content of 30% to 46%. The main raw materials are clay clinker or light clinker and plastic clay. They are usually produced by combustible methods, and can also be produced by chemical methods or foam methods to form a porous structure.

The ingredients are mixed with water to make plastic clay or mud, which is molded by extrusion or pouring, and fired in an oxidizing atmosphere at 1250-1350°C after drying.

The bulk density of commonly used lightweight clay bricks is 0.7-1.2g/cm3, the compressive strength is 2.0-5.9Mpa, and the thermal conductivity is 0.221-0. 442W/(m·K) (1350°C).

Lightweight clay bricks have a wide range of uses, mainly used in various industrial kilns as heat insulation materials that do not contact molten materials and have no erosive gas effect, and the service temperature is 1200-1400 °C.

The Chinese standard (GB3994-1983) is divided into NG-1.5, NG-1.3a, NG-1.3b and other grades according to the volume density, and lists different models of clay heat-insulating refractory bricks.
