摘要: Abstract By adding various nucleants in the selenide glasses, glass-ceramics of high crystallinity are produced after heat treatment. The variation a number physical properties certain as function crystallization treatment is reported. studied include thermal expansion, microhardness, fracture toughness, sag point and infrared transmission. It shown that most strongly dependent on microstructure glass-ceramics.
