  • Production of beryllium oxide powders with controlled morphology and quality
    Patent number: 5268334
    Abstract: A process for producing beryllium oxide (BeO) from beryllium hydroxide (Be(OH).sub.2) in a single reactive step. Beryllium hydroxide powder is mixed with a calcination additive containing Mg and/or Ca and calcined at 1000.degree.-1300.degree. C. The resultant oxide pow-der is characterized by low fluorine content (<100 ppm), low surface area (<1.5 m.sup.2 /g) and a controlled particle size of 2 .mu.m to 25 .mu.m.
