PRODUCTION ENGINEERING MEASURE FOR BERYLLIUM OXIDE AND PARTS PRODUCED FROM IMPORTED ORES.

Abstract

Four uniform powder batches were prepared in the pilot plant using processes developed for this contract. The powder batches met all tentative specifications. A fabrication mix was prepared from each powder batch. The mixes met all chemical and physical property specifications. Test specimens were produced from each powder batch using pressing conditions, green densities, and firing schedules approximating conditions that will be employed to produce the final parts for the contract. The final specimen sizes and property measurements were as per MIL-I-10A requirements. Dielectric constant and loss factor values measured at one megacycle, met required specifications. Flexural strength values met required specifications. Thermal conductivity results at 100F and 280F were equal to or greater than proposed specifications set earlier for quality BeO ceramics.
