BERYLLIUM OXIDE CERAMIC Introduction Beryllium Oxide (BeO), which is commonly referred to as beryllia ceramics. Beryllia Ceramic’s thermal conductivity(equivalent to aluminum) is second only to diamond , it has superior performance at high temperatures, high insulation and excellent mechanical, electrical, microwave properties and high thermal stability. No other material can economically deliver the same performance and reliability demanded by today’s high-tech products and systems. Above advantages, has created a market demand for beryllium oxide (BeO) ceramic, or beryllia. Toxicity Isuue Regarding the toxicity of beryllium, it refers soluble beryllium oxide is toxic, our beryllium oxide ceramics is sintered at 1650-1700 ° C high temperatures and it is finished ceramic material which is insoluble in acids and alkali, therefore through proper protection, our beryllium oxide ceramics is not toxic.
