摘要：NOVELTY - A quantity of nitride is introduced into sulfide series glass and after melting, oxide impurities residual in the original sulfide series glass can be effectively removed., so that the infrared transparence of glass is raised, and at the same time the introduction of three coordinated N has the obvious influence on the glass structure so as to raise the transition temp. and micro-hardness of the glass. USE - Sulphide series glass. ADVANTAGE - IR transparency of the glass, the transition temperature and the microhardness of the glass is increased.
