Ceramic cartridge heater
Ozark Ceramics Europe

OZARK extrudes insulators from MgO, Al2O3, and HfO2 for use in production of mineral insulated thermocouple cable, cartridge heaters, and other high temperature and electrical applications. Extrusion is a ceramic manufacturing technique which produces any shape with a constant cross section and theoretically
unlimited length. A mix containing the desired ceramic powder and various organic additives is forced through a die opening configured to give the required geometry which may include holes of precise shape and size. The extrudate is subsequently dried, fired, cut, inspected and packaged for shipment. Precise control of process variables is required to obtain high quality extrusions meeting purity, microstructural, and dimensional specifications.
