Mar 28 2021 · 1. Introduction. The first debates about the supply risk of strategic materials date back to the late 1930s but in the last ten years a great concern has arisen about the supply security of metals and other strategic elements especially from import-dependent industrialized countries such as the EU Japan and USA whose high-tech products are strongly dependent on them.

Since anatase is metastable phase we could observe no clear diffraction pattern of anatase in the Bi-containing CaBBAT glass-ceramics with various heat-treatment conditions. Therefore we can conclude that the addition of ZnO improves the transparency of the TiO2 glass-ceramics and affects the crystallization of metastable phase.

Gamma ray irradiation had an important effect on the microstructure of chromium carbide nanopowders. The interplanar spacings of chromium carbide (110) crystal faces before and after gamma ray irradiation were 0.3725 nm and 0.3824 nm respectively. The crystal structure of chromium carbide was changed by gamma ray irradiation.
