摘要:

Ceramics usually have irregular grains, cracking, or porosity, which result in their lightproof. Y2Mo3O12 ceramics have more porosity due to the heavy hygroscopicity. Introducing ZnLi to Y2Mo3O12 could form regular grains, reduce cracking and porosity. With increasing the content of ZnLi, the grain shapes self-assembly gradually and then the laser scattering and transmittance improve. The laser scattering property and transmittance of diverging rays become the best in ceramics Y2-x(ZnLi)xMo3O12 (x=1.0 and 1.2) with regular grains and low thermal expansion. The formation mechanism of regular grains is ascribed to the substitutions of Zn2+ and Li+ for Y3+ in Y2Mo3O12 resulting in the preferential growth. The investigation in laser scattering, transmittance and low thermal expansion behaviors of Y2-x(ZnLi)xMo3O12 could pave a way to weaken the strong-laser attack from the high-power laser weapon and the other.

With increasing the content of ZnLi, the grain shapes self-assembly gradually and then the laser scattering and transmittance improve. The laser scattering property and transmittance of diverging rays become the best in ceramics Y2-x(ZnLi)xMo3O12 (x=1.0 and 1.2) with regular grains and low thermal expansion. The formation mechanism of regular grains is ascribed to the substitutions of Zn2+ and Li+ for Y3+ in Y2Mo3O12 resulting in the preferential growth. The investigation in laser scattering, transmittance and low thermal expansion behaviors of Y2-x(ZnLi)xMo3O12 could pave a way to weaken the strong-laser attack from the high-power laser weapon and the other.
