八十年代中后期以来,伴随着电子工业的迅速发展,电子陶瓷管也取得了突破性的进展。由于展其耐高温、抗形变、高度纯、污染少,因而人们寄于厚望。目前在日本、美国、西欧等工业发达国家均已相继采用电子陶瓷管取代传统的石英玻璃管作为半导体基片pn结 Since the middle and late eighties, along with the rapid development of the electronics industry, electronic ceramic tubes have also made breakthrough progress. Due to its high temperature resistance, deformation resistance, high purity, less pollution, so people send high hopes. Currently in Japan, the United States, Western Europe and other industrialized countries have been using electronic ceramic tube to replace the traditional quartz glass tube as a semiconductor substrate pn junction
