โœฆ Synopsis

Isothermal sintering of Monobarium aluminate (BaA1204) has been carried out by measuring shrinkage on firing of compacted pellets of -45 micron size powder 145oOc. samples at temperature of 1300,1350,1400 and 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-' (-188,000 _________ ) cm 2 -1 set, RT

Structural, ferroelectric, pyroelectric, and optical properties of ceramics and crystals of \(\mathrm{BaAl}_{2} \mathrm{O}_{4}\) have been investigated. A refinement of the atomic positions has been carried out from the X-ray powder data. \(\mathrm{BaAl}_{2} \mathrm{O}_{4}\) shows anomalous behavior
