摘要：

Isothermal sintering of Monobarium aluminate (BaAl2O4) has been carried out by measuring shrinkage on firing of compacted pellets of -45 micron size powder samples at temperature of 1300, 1350, 1400 and 1450 degrees C. The time dependence of linear shrinkage reveals volume diffusion as dominant mechanism of sintering. The apparent diffusion coefficient (D) of sintering has been calculated and its temperature dependence can be represented by the equation, D = 8.04x10(-9) (- 188,000/R T) cm(2) sec(-1).
