摘要
微晶玻璃,是由玻璃经受控热处理得到的多晶固体,具有机械强度高、热膨胀系数可调、热稳定性好、化学稳定性好、低介电损耗、电绝缘性好的特点。依据1985年至今的微晶玻璃相关中国专利申请,分析了微晶玻璃制造技术在建筑材料、化学工业、机械工业、电子工业以及生物医学领域的发展和应用情况。
Glass-ceramic is a polycrystalline solid obtained by controlled heat treatment of glass. It has the characteristics of high mechanical strength, adjustable thermal expansion coefficient, good thermal stability, good chemical stability, low dielectric loss and good electrical insulation. Based on the patent applications in China related to glass-ceramics from 1985 to the present, this paper analyzes the development and application of glass-ceramic manufacturing technology in the fields of building materials, chemical industry, machinery industry, electronics industry and biomedicine.
