Ceramic ball is a rolling spherical element. These are used in various check and ball valves, bearing and many other mechanical devices that provide linear and rotary motion. These ceramic ball bearings are made of inorganic, non-metallic elements that are processed or used at high temperatures. An important physical specification among all ceramic balls is the outer diameter or width. Through precision grinding all cuts, scratches, scuffs, and any other breaks in the surface to ensure a smooth surface. As compared to steel balls many ceramic balls are much harder thereby, which they result in a longer life, are more reliable.

Ceramic Band Heaters are specifically designed to meet the increasing demand for energy conservation and to improve operation efficiency. These are capable of generating the higher temperatures essential to process today's high temperature resins. Electrical energy savings are achieved by using a 1/4″ thick ceramic fiber insulating blanket, reducing power consumption by 25 to 30 percent. Because of the low thermal conductivity of the ceramic fiber insulation, the external surface temperature of the ceramic band heater is approximately 400°F while running the inside surface temperature at 1200°F. They transmit heat through both conduction and radiation. The element winding is designed to run at maximum temperature and heat the ceramic blocks to the point at which they radiate energy into the barrel as well as conduct energy by being in contact with the barrel.

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.
