在二战后的冷战时期，美国、西欧和日本等西方国家由于担心耐热钢的基本原料成分锰、钴、铬、镍等可能缺乏，因而把注意力投向用陶瓷耐热材料替代耐热钢，由此各国都掀起了陶瓷研究热，先后开发成功性能优良的高温高强度陶瓷，并开始商品化。但是，随着世界政局的缓和，军... In the Cold War era after World War II, Western countries such as the United States, Western Europe and Japan were concerned about the possible lack of manganese, cobalt, chromium and nickel, which are the basic raw materials for heat-resistant steels, so they turned their attention to heat resistant steel instead of heat- Thus all countries have set off a ceramic research fever, has developed a successful high-performance high-performance high-strength ceramic, and began commercialization. However, with the ease of the world political situation, the military ...
