六、电子陶瓷材料随着陶瓷制造技术的日益进步,精密陶瓷已远远超出了硅酸盐的范围,现已包括各种氧化物、复合氧化物、非氧化物、半导体以及各种复合物等范围十分广泛的材料。作为电子陶瓷,上述这些材料有不少是以半导体的形态被使用的,如按工作原理分类,则可分为:利用晶粒本身的性质、利用晶界以及晶界析出相的性质、利用陶瓷表面的性质等几种类型,如表1。表中未包括光电陶瓷材料,有关内容后面还要专门叙述。下面 Six, electronic ceramic materials With the continuous improvement of ceramic manufacturing technology, precision ceramic has far exceeded the scope of silicate, now includes a variety of oxides, composite oxides, non-oxides, semiconductors and various compounds A wide range of materials. As electronic ceramics, many of these materials are used in the form of semiconductors, such as classified according to the working principle, can be divided into: the use of the nature of the grain itself, the use of grain boundaries and grain boundary precipitation of nature, the use of ceramics The nature of the surface, such as several types, such as Table 1. Table does not include optoelectronic ceramic materials, the content behind the special narrative. the following
