Ceramic rods and bars are easily machinable and have excellent resistance to high temperatures, abrasives and chemicals with low thermal conductivity. Although the nature of ceramics means that some may show poor shock resistance, they are tough and highly polish-able considering their comparatively low densities.
Comprised of non-organic, non-metallic materials, they are radiation resistant and lead-free. Ceramics hold tight tolerances for electrical insulators with zero porosity and no out-gassing, they can also be soldered to a wide range of materials.
Ceramics are usually made by mixing together clay, earthen elements, powders and water. They are then shaped into whatever form they will be used to produce the desired outcome. After this has been done the Ceramic is then fired in a high-temperature oven known as a kiln.
