What are the differences between antistatic ceramics and conductive ceramics?
Some ceramic oxide conductive ceramic is heated, electrons in atomic layer can obtain enough energy to overcome the nucleus of its appeal, and become a free electron movement, the ceramic becomes conductive ceramics.
The anti-static ceramic material is generally used for composite technology, Sb doped SnO2 was added to the ceramic glaze, firing melt layer will be formed after the rich semiconductor components in the semiconductor contact layer surrounding the melt formed a good conductive network, so that the glaze resistance decreased, the conductive particles form continuousconducting in ceramics and when the surface resistance of materials is 105 to 109 Omega, the electrostatic charges will be released as soon as possible, so as to achieve the antistatic effect.
(now has developed a variety of high temperature electronic conductive ceramic materials: silicon carbide ceramic highest use temperature is 1450 DEG C, the highest temperature of two molybdenum silicide ceramics is 1650 DEG C, the highest temperature of zirconia ceramics is 2000 DEG C, the highest use temperature of thoria ceramics as high as 2500 degrees Celsius.)
