こ七を目的とず為。Ribbed barium titanate porcelain has traditionally been avoided as a material for ceramic condensers in high-R trains. However, this material has a high sintering temperature of 1', 300 to 1400'C. When producing R-layer ceramic capacitors, the disadvantage of the present invention is that an expensive internal mold mainly composed of platinum or palladium must be used at a temperature higher than the sintering temperature. Purpose □ The present invention improves the above-mentioned drawbacks and achieves a sintering temperature of 1000 °C.
The purpose of this invention is to provide a porcelain composition with a low dielectric constant and a high dielectric constant.

It can be sintered at low temperatures. In addition, the dielectric voltage junction is small, the temperature change rate of the dielectric constant ε is small,
It exhibits features such as relatively high specific resistance.

! The temperature change rate and dielectric voltage contact are relatively small, and the resistivity is large, making it suitable for use as a material for ceramics and capacitors.In addition, it can be fired at a low temperature of 1000°C or less, allowing the use of inexpensive materials for the firing furnace. It has great industrial value in that it can be made and requires less energy for firing.
When using a multilayer ceramic capacitor V, the sintering degree is low, so it is possible to use internal electrodes made of silver, which is comparatively cheaper, and the price of the capacitor can be lowered, making it an industrial choice. profits are large.
