ceramic insulator tube for corona electrode


Alumina ceramic (also called al2o3 or aluminum oxide ceramic) is widely applied in high temperature fields because of their good resistance to high temperature, it can withstand high temperature up to 1800℃, in addtion to its stable chemical properties, high mechanical strength and electrical insulation, alumina ceramic is widely used to make ceramic tubes for high temperature furnace, one end closed ceramic tubes or multi-hole insulating rods for thermocoulples, square ceramic tubes for corona electrode. Mascera is able to produce ceramic tubes as long as 2000mm using the extrusion molding technology, custom size is available, please contact us when you have any demand.
