Abstract

The temperatures of devitrification of cold crystallization, melting, and glass transition of samples of the CaO–B₂O₃–Al₂O₃–CuO system are determined by the methods of differential thermal analysis. The viscosity of alumina–calcium borate melts containing up to 8.1% of CuO is measured in the temperature range of 880 to 1300°C. It is shown that the addition of copper oxide reduces the viscosity and activation energy of the viscous flow.

摘要

CaO-B ₂ O ₃ -Al ₂ O ₃ -CuO体系样品的冷结晶、熔融和玻璃化转变温度采用差热分析法测定。在 880 至 1300°C 的温度范围内测量含有高达 8.1% 的 CuO 的氧化铝-硼酸钙熔体的粘度。结果表明，氧化铜的加入降低了粘性流的粘度和活化能。
