Glass Formation in Chalcogenide Systems and the Periodic System of Elements
Glassy semiconductor alloys are synthesized as a rule from elemental substances of equal degree of purity. To obtain most glassy alloys, materials of “very pure” grade are used. The total weight of the obtained glassy alloy is determined mainly by its crystallizing ability. Glasses of low crystallizing ability can be synthesized in any amount. Easily crystallizing glasses can be synthesized in amounts 10–5 g and less. The smaller the total weight of the melt, the higher the rate at which this melt can be cooled uniformly. In the Semiconductor Chemistry Laboratory of the Leningrad State University the glasses are synthesized as a rule with a total weight of 5 g.
