Alumina Ceramic Furnace Tube
My factory looking for distributors.
Alumina ceramics are products made from the chemical compound with the same name, alumina ceramic. Alumina ceramic, also known as aluminum oxide, is a combination of aluminum and oxygen. It occurs naturally, most often as corundum, as crystalline form of the compound that, when gem quality, manifests as sapphire or ruby. Alumina ceramic is extremely hard and durable, resistant to compressive strength, resistant to weathering, resistant to chemicals, electrically insulating, highly dense and stiff and incredibly thermally conductive. In fact, it is up to twenty times more thermally conductive than the majority of other oxides. In addition, it is quite cost effective. These qualities make alumina ceramics ideal for a wide variety of industrial and commercial applications, including: automotive and aerospace engineering, medical instrument fabrication, prosthetic limb creation, ballistic ceramic armor creation, metalizing, seal ring fabrication, welding, plating and the pre-finishing of wood flooring.
Alumina furnace tube are often used in various tube furnaces, vacuum furnaces, heating furnaces and high temperature furnaces.
The purpose of the alumina furnace tube is to be used as the lining of various test electric furnaces, which mainly separates the heating element from the burned test substance, closes the heating area and places the burned test substance. Alumina furnace tubes have a wide range of applications, involving high temperature test and analysis equipment in various industries, such as coal test and analysis equipment, metallurgical powder test and analysis equipment, chemical and glass industry test and analysis equipment, etc.
