Y-12 Development Organization technical progress report period ending March 1, 1995. Part 5, Ceramics/plastics/carbon materials development

PDF Version Also Available for Download.

Description

The preparation of small-scale-Production crucibles by plasma-spraying of TRIBOCOR onto niobium is continuing. Microwave heat-treatment of this size crucible has been demonstrated successfully. Conventional plasma-spray coating appears to offer advantages over ``vacuum`` plasma-spraying for preparing the coatings. Encapsulant/stucco ``shells`` for ``casketing`` boron carbide (B{sub 4}C) or silicon carbide (SiC) results in consistent attainment of the necessary {ge}2100C processing temperatures for these nonoxide materials. Gelcasting is an excellent technique for making shapes with both B{sub 4}C and SiC. Tiles of B{sub 4}C were prepared and will be microwave sintered soon.
