Preparation of Barium Aluminate with BaCO_3 and Al(OH)_3

摘要

Synthesizing barium aluminate using barium carbonate and aluminium hydroxide, the optimum conditions in reaction process of synthesizing barium aluminate were discussed. The phase of the products was characterized by XRD. The results indicate that the optimal synthesizing conditions are established with the yield of 88.43% when the roasting time is 80min, the roasting temperature is 1350°C and molecular proportion of Al_20_3/BaO is 1.1. The bulk density of barium aluminate is 1.5g/cm~3;;average particle size is 89.808μm;;surface mean size is 65.915um;;and the specific surface area is 0.0246016m~2/g.
