• Unshaped Refractory Materials

          Unshaped refractory materials are defined as” mixtures consisting of aggregates, additives, and binders, prepared for direct use in the state of delivery or after adding suited liquids”. In contrast to refractory bricks, they are without specific shape and are in majority placed in larger sections behind molds and templates forming a monolithic lining. Gunning installations without the requirement for a mold are increasing due to ease of application and higher installation speed.

China tabular alumina for export

Tabular Alumina Properties:

1)Tabular alumina price has high purity, good volume stability, minimal re-burning shrinkage, for the production of refractory or castable high-temperature treatment has good thermal shock stability and bending strength.

2) The crystal of tabular alumina price staggered plate shape, to increase the mechanical strength of the particles; interior structure full of closed pores, high bulk density, low apparent porosity, low water absorption, to reduce the amount of fluid re-use productions.

3) High refractoriness high corrosion resistance high erosion resistance, excellent thermal shock resistance, low shrinkage and good thermal load strength etc.

4) Meanwhile, high-purity avoiding damage to system, it is an ideal material for making refractory material, ceramic material and insulating materials
