Laser scattering,transmittance and low thermal expansion behaviors in Y_(2-x)(ZnLi)_xMo_3O_(12) by forming regular grains

Ceramics usually have irregular grains, cracking, or porosity, which result in their lightproof.Y_2Mo_3O_(12) ceramics have more porosity due to the heavy hygroscopicity.Introducing ZnLi to Y_2Mo_3O_(12) 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 Y_(2-x)(ZnLi)_xMo_3O_(12)(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 Zn~(2+)and Li+for Y~(3+) in Y_2Mo_3O_(12) resulting in the preferential growth.The investigation in laser scattering, transmittance and low thermal expansion behaviors of Y_(2-x)(ZnLi)_xMo_3O_(12) could pave a way to weaken the strong-laser attack from the high-power laser weapon and the other.
