工程陶瓷由于具有强度高、抗酸碱、耐腐蚀、耐高温和热稳定性好等一系列优良特性,因此,国外科技界将它作为20世纪的一种新材料,投入大量的人力和物力重点研究开发。现在,国外已研制成了陶瓷弹簧、精密机床主轴、陶瓷发动机、陶瓷医疗器械和陶瓷橱衬板等。在国内,陶瓷作为密封件,用于有腐蚀作用的各种石油化工泵,作为耐磨的喷砂嘴用于喷砂机上,也 Due to its high strength, anti-acid and alkali resistance, corrosion resistance, high temperature resistance and good thermal stability, engineering ceramics have put a lot of manpower and material resources into consideration as a new material in the 20th century by foreign science and technology circles research and develop. Now, foreign countries have developed a ceramic springs, precision machine tool spindles, ceramic engines, ceramic medical equipment and ceramic cabinet liner. In China, ceramics as a seal for a variety of petrochemical pump corrosion, as a wear-resistant spray nozzle for sandblasting machine, also
