摘要:

透明微晶玻璃既具有陶瓷固有的耐高溫、耐腐蝕、高絕緣、高強度等特性，也具有比晶體材料制備工藝簡單、易做成大尺寸及受雜質影響小的優點，還具有玻璃的光學特性，在固體激光器、紅外發生器、紅外探測器、紅外整流罩、核成像與核探測、高能粒子探測、X射線斷層掃描、防護面具、照明和信息等軍民用領域都有極為重要的應用，是一類對國家安全和國民經濟可持續發展具有重大意義的新一代材料，可望替代國內目前不能生產及制備技術和性能與國外差距較大的透明晶體和透明陶瓷材料，是當前材料領域研究和應用方面的重要前沿方向。本文簡要介紹高結晶度透明微晶玻璃研究新進展，主要包括稀土摻雜Na2O-CaO-SiO2(NCS)、MgO-Al2O3-SiO2(MAS)、TeO2-Bi2O3-ZnO(TBZ)、Gd2O3-SiO2(GSO)、Gd2O3-Ga2O3-GeO2 (GGG)等體系透明微晶玻璃的研究現狀和發展趨勢。

Abstract:

High crystalline transparent glass-ceramic has a wide range of applications in solid state laser, infrared generator, infrared detector, infrared domes, nuclear imaging and detecting, high-energy particle detectors ，CT scanner,window masks, lighting and information fields due to its many excellent properties,.such as the inherent characteristics of high temperature resistance, corrosion resistance, high insulation and high strength similar to transparent ceramics.Compared to the crystals with high transmittance, the transparent glass-ceramic has also many advantages including simple process, large size and less influence from impurity. Obviously,high crystalline transparent glass-ceramic is a kind of new generation materials with great significance to national security and sustainable development of national economy and can be expected to replace transparent crystal and transparent ceramic materials which are difficult to prepare by using present technology and equipment.In this paper,some new progress of development in high crystallinity and transparent glass ceramics is briefly introduced,focusing on the research status and trend of Na2O-CaO-SiO2 (NCS), MgO-Al2O3-SiO2 (MAS), TeO2-Bi2O3-ZnO (TBZ), Gd2O3-SiO2 (GSO) and Gd2O3-Ga2O3-GeO2 (GGG) systems.
