Chalcogenide glass in the ternary Ge-Sb-Se system is inherently moldable. thus being considered as a strong candidate material for use in infrared-transmitting lens applications from the viewpoint of thermal and mechanical stability. In an effort to experimentally determine compositional region suitable for the molded lens applications. we evaluate its compositional dependence of hard... https://parisnaturalfoodes.shop/product-category/apricot/
