Description
Alumina fiber blanket is a blanket-like product made of alumina fiber cotton under specific conditions through dry needle punching process, without any organic binder or other additives.
The alumina content of the product: 71%-73%, has excellent chemical properties, and shows excellent high temperature resistance in high temperature applications.
Products are widely used in high-temperature fields of 1250°C-1500°C in various industries to solve problems such as fire resistance, heat insulation, and fire prevention. It can be used as gap filling and sealing materials in high temperature fields, and raw materials for other high temperature resistant products.

High-quality crystals may be grown hydrothermally, or otherwise by the Verneuil method. For the most part, beryllium oxide is produced as a white amorphous powder, sintered into larger shapes. Impurities, like carbon, can give a variety of colours to the otherwise colourless host crystals.
Sintered beryllium oxide is a very stable ceramic. Beryllium oxide is used in rocket engines and as a transparent protective over-coating on aluminised telescope mirrors.
Beryllium oxide is used in many high-performance semiconductor parts for applications such as radio equipment because it has good thermal conductivity while also being a good electrical insulator. It is used as a filler in some thermal interface materials such as thermal grease.Some power semiconductor devices have used beryllium oxide ceramic between the silicon chip and the metal mounting base of the package to achieve a lower value of thermal resistance than a similar construction of aluminium oxide. It is also used as a structural ceramic for high-performance microwave devices, vacuum tubes, magnetrons, and gas lasers. BeO has been proposed as a neutron moderator for naval marine high-temperature gas-cooled reactors (MGCR), as well as NASA's Kilopower nuclear reactor for space applications.
