Metal Fluorides Produced Using Chlorine Trifluoride Gas
For developing coating materials, the fluorides of scandium, lanthanum, strontium, barium, magnesium and aluminum were produced from their oxides and chlorides by means of exposure to chlorine trifluoride gas at temperatures between room temperature and 700°C. The metal chlorides could be easily fluorinated even at room temperature, while the metal oxides required temperatures higher than 300?C.

Silicon Carbide was first prepared in the early 1800''s. It was in commercial production by 1892, as a powder for grinding and cutting, having a Mohs hardness of 9-10 (almost as hard as Diamond). Nicalon continuous multi-filament tow consists of fine filaments of ultra …
Hardness and Young''s modulus of amorphous a-SiC thin films
Due to its interesting mechanical properties, silicon carbide is an excellent material for many appliions. In this paper, we report on the mechanical properties of amorphous hydrogenated or hydrogen-free silicon carbide thin films deposited by using different deposition techniques, namely plasma enhanced chemical vapor deposition (PECVD), laser ablation deposition (LAD), and triode
