heal.abstractThe suitability of three new glass compositions for producing diopside-Ca-Tschermak clinopyroxene based glass-ceramics (GCs) was investigated. With respect to the formula of diopside, the first investigated composition resulted from the substitution 0.2(Si4+ + Mg2+) <-> 0.4 Al3+, which leads to a composition of 80 mol.% diopside and 20 mol.% Ca-Tschermak. The substitutions in the second compositions were 0.25(Ca2+ + Si4+) <-> 0.25 (Y3+ + B3+) and 0.2(Si4+ + Mg2+) <-> 0.4Al(3+), and in the third composition 0.2Ba(2+) <-> 0.2Ca(2+) and 0.2(Si4+ + Mg2+) <-> 0.2(B3+ + Al3+). The influence of these substitutions on glass crystallization and the properties of the GCs produced between 850 and 1000 degrees C was experimentally investigated. The experimental results showed that the easily cast glasses, after melting at 1580 'C for 1 h, are prone to surface crystallization. Augite is predominantly crystallized, but Ca- and Ba-alummosilicates can also form, according to the substitutions. The stability of the assemblage of the crystalline phases over a wide temperature range (850-1000 degrees C) and prolonged heat treatment (up to 50h) and the properties of the produced M indicate a high potential of these compositions for several functional applications.
