A ceramic capacitor is so named because of the use of ceramic dielectrics. One type of ceramic capacitor uses a hollow ceramic cylinder as both the form on which to construct the capacitor and as the dielectric material. The plate consist of thin films of metal deposited on the ceramic cylinder. A second type of ceramic capacitor is manufactured in the shape of a disk. After leads are attached to each side of the capacitor, the capacitor is completely covered with an insulating moisture-proof coating. Ceramic capacitors usually range in value between 1 picofarad and 0.01 microfarad and may be used with voltages as high as 30,000 volts.
Ceramic Cements are suitable for thin film bonding and coating applications from 2 to 125 mils. These involve the evaporation of water and are indefinite and final cure occurs between 18 and 24 hours. These products are all single component silicates. It provides high electrical insulation and thermal conductivity.
