材料,是今日和今后新技术和新产品的基础,新技术有赖于新材料的开发,而新材料将促进新技术的发展。故国外把材料列为新的产业革命大力发展的一个领域。现简述无机功能材料的广泛应用可见一斑。1.电磁材料它是无机功能材料中最早供实用的一类材料。广泛用于我们常见的电气产品中,如电视机、洗涤机、制冷机、导向装置、录象磁带、自动售货机、自动剪票口和计算机。氧化铝陶瓷因其绝缘性能优良,被用作集成电路衬底材料。钛酸钡、锆钛酸铅之类铁电体,因其介电常数高,故用于制造大容量电容器,又因其压电效应,故用于制作点火器的元件、扩音器、鱼群探测器等音响装置。β-Al_2O_3现正在研制用于能在300℃下工作的电动汽车用的钠-硫电池的隔
Materials, which are the basis for new technologies and products today and in the future, depend on the development of new materials that will facilitate the development of new technologies. Therefore, foreign materials as a new industry revolution vigorously develop an area. Now briefly described inorganic functional materials can be seen a wide range of applications. 1. Electromagnetic material It is the earliest available inorganic functional materials for a class of materials. Widely used in our common electrical products, such as televisions, washing machines, chillers, guides, video tapes, vending machines, automatic ticket gates and computers. Alumina ceramics are used as an integrated circuit substrate material because of their excellent insulating properties. Barium titanate, lead zirconate titanate and other ferroelectrics, because of its high dielectric constant, it is used in the manufacture of high-capacity capacitors, because of its piezoelectric effect, it is used to make the ignition components, amplifiers, fish Group detectors and other audio devices. β-Al_2O_3 is currently being developed for use in 300 ℃ can be used for electric vehicles with sodium-sulfur battery compartment
