Description

technical field [0001] The invention relates to the technical field of conductive ceramics, in particular to a conductive ceramic and a method for preparing the conductive ceramic by using silicon carbide. Background technique [0002] Usually ceramics do not conduct electricity and are good insulators. For example, in oxide ceramics, the outer electrons of atoms are usually attracted by the nucleus and bound around the respective atoms, unable to move freely. So oxide ceramics are usually non-conductive insulators. However, when some oxide ceramics are heated, the electrons in the outer layer of atoms can gain enough energy to overcome the attraction of the atomic nucleus to it and become free electrons that can move freely, and this ceramic becomes a conductive ceramic. Conductive ceramics have a wide range of applications, and the added value of products is higher than ordinary ceramics. At present, the varieties of conductive ceramics on the market are limited, which ...
