Tabular conundum castable with high purty and high meling point of tabular conundum as main raw materials, with high qually acivated alumina powder as raw materials, creep resistance of high thermal shock resistance, anti-spalling, high refractoriness, structural stabiity, high temperature properties and wear resistance increased significantty. At the same time, by increasing the silicon cartide, greatly enhancing the comosion resistance of conundum castable. Mainly usod for kilns and burmer.
Tabular alumina has good heat resistance and good bulk temperature thermal shock capabilities. The crystal staggered plate shape, to increasing the mechanical strength of the particles
