Using SPC for the dry-pressing of beryllia parts

Recent advances in the development of high-power electronic devices require the use of materials which are both good electrical insulators and good thermal conductors. Beryllia ceramics exhibit excellent electrical and thermal management performance. Production of beryllia parts requires consistent, ceramic-grade powders and reliable fabrication processes. The extractive process, dry-pressing fabrication process, and the application of statistical process control techniques are reviewed. The important mechanical, thermal, and electrical properties of beryllia are compared to other common ceramic materials.
