Fabrication Studies of Ternary Rare Earth Sulfides for Infrared Applications.
Abstract
Homogeneous, phase pure powders of cubic CaLa2S4 have been synthesized. The process developed has yielded powder with very fine particle size without the need for milling or mixing. The processing time has also, been substantially reduced. It appears that the purity and morphology of these powders will allow one to produce highly transparent window blanks using standard sintering and/or hot isostatic pressing techniques. Although initial single crystal growth experiments have failed to produce useful samples, other approaches remain to be explored. However, it now appears that the more direct powder processing methods will be capable of producing optical quality material and, in fact, is the approach of more practical interest. (Author)
