Brief Introduction for beryllium oxide ceramics

Beryllium oxide ceramic is an excellent structural ceramic material with high thermal conductivity, high melting point, high strength, high insulation, high chemical and thermal stability, low dielectric constant, low dielectric loss, and good process adaptability. And other characteristics, it has been widely used in the fields of special metallurgy, vacuum electronics, nuclear technology, microelectronics and optoelectronics.

1. Current Status of Beryllium Oxide Ceramics

The development of beryllium oxide ceramics in China began in the 1930s, but it was not a period of rapid development until the late 1950s and late 1970s.

The United States is one of the countries in the world that mainly produces and consumes beryllium oxide ceramics. It is also the country with the largest output of beryllia ceramic products, the best technical product performance, and the highest production technology in the world. Brush Welman is one of the largest beryllium oxide powder and ceramic product manufacturing companies in the United States and the world. In addition, the Ulbinsky Metal Factory in Kazakhstan is also a major manufacturer of BeO production and scientific research.

2.Notes on the production of beryllium oxide ceramics

Although high-purity beryllium oxide ceramics are very safe, it cannot be ignored that beryllium oxide dust is toxic to the human body. This is similar to the fact that plastics do not produce toxins when used, but the materials made of plastics are generally toxic. The reason is that beryllium oxide ceramics processed into solid form do not cause special harm to human health. Many countries, including China, have included beryllium oxide powder as a class of dangerous goods. To avoid pollution and threats as much as possible, producers need to be fully aware of the toxicity of beryllium oxide ceramic powders. The regulatory agency shall improve the rules and regulations for the operation and protection of beryllium oxide dust, strengthen investment in the safety protection of beryllium oxide production enterprises and personnel, and establish practical and effective beryllium oxide operation instructions. And a series of measures such as effective and clear identification of all beryllium oxide ceramic related products, these can become protective "barriers" for the safe production of beryllium oxide ceramics manufacturers.
