Effect of Process Variables on Fired Properties of Bauxite from Rajhauan (UP)

The effects of varying forming pressure, firing temperature and type of bond on the fired properties of Rajhauan (UP) bauxite are reported. The porosity and water absorption were found to decrease with increasing forming pressure and firing temperature. Bulk density was found to increase with increasing forming pressure and firing temperature. The firing shrinkage increased with increasing firing temperature and decreased with decreasing forming pressure. The PCE and RUL values were reasonably good. It was concluded that the material could be used for making refractories.
