碳和石墨制品是由固体碳素颗粒与适量粘结剂经混捏、成型、焙烧或石墨化高温热处理而制得的。由于粘结剂煤沥青的结焦残碳率一般在50％左右,以及固体碳素颗粒在整个热处理过程中不发生熔融变形,因此碳和石墨制品具有较高的气孔率(孔度)、结构均匀程度差、颗粒界限比较明显等特点。本文从碳和石墨制品的两个基本组成部分(基质和孔隙)出发,研究了他们的结构特点,以及这些特点的一般评述方法。为了获得石墨制品真实、清晰的显微结构 Carbon and graphite products are made by solid carbon granule and the appropriate amount of binder by kneading, forming, calcination or graphitization heat treatment. As the binder coal tar pitch coking residual carbon rate is generally about 50%, and solid carbon particles in the entire heat treatment process does not occur melting deformation, so carbon and graphite products have high porosity (porosity), uniform structure The degree of difference, the particle boundaries more obvious and so on. In this paper, starting from the two basic components of carbon and graphite products (matrix and porosity), their structural characteristics and general comments on these characteristics are studied. In order to obtain a real, clear microstructure of graphite products
