这里所说的瓷介就是用电容器瓷制成的陶瓷介质。
大家知道，陶瓷是一类质硬、性脆的无机烧结体。
就其显微结构而论，大都具有多晶多相结构。
其性能往往决定于其成份和结构。
当配方确定之后，能否达到预期的效果，关键取决于制造陶瓷粉料的工艺。
按其用途可以分为三类：①高频热补偿电容器瓷（UJ、SL）；②高频热稳定电容器瓷（NPO）；③低频高介电容器瓷（X7R、Y5V、Z5U）。
按温度系数分可以分为两类：①负温度系数电容器瓷（即高频热补偿电容器瓷）；②正温度系数电容器瓷（即平时我们常说的COG、X7R、Y5V瓷料）。
按工作频率可以分为三类：低频、高频、微波介质。
高频热补偿、热稳定电容器瓷是专供Ⅰ类瓷介电容器作介质用，其瓷料主要成分是MgTiO3、CaTiO3、SrTiO3和TiO2再加入适量的稀土类氧化物等配制而成。
其特点是介质系数较大，介质损耗小，温度系数和范围广，一般在（+120～-5600）ppm/℃之间可调。
高频热补偿电容瓷常用来制造的负温产品，其用途最广的地方就是振荡回路，像彩电高频头。
大家知道，振荡回路都是由电感和电容构成，回路中的电感线圈一般具有正的电感温度系数。
因此，为了保持振荡回路中频率(F=1/2π√LC)不随温度变化而发生漂移，就必须先用具有适当的负温度系数的电容器来进行补偿。
低频高介电容器是指强介铁电陶瓷，一般用作Ⅱ类瓷介电容器的介质。
具有自发极化性质的非线性陶瓷材料，一般以钛酸钡（BaTiO3）为主体的铁电陶瓷，其特点是介电系数特别高，一般数千，甚至上万；介电系数随温度呈非线性变化，介电常数随施加的外电场有非线性关系。
