| Abstract |
"Fine" in "fine ceramic powders" refers both to their quality and their granulation (1-10µm). They have many uses, including abrasives, lubricants and additives to confer strength on various products. Of 29 kinds tested for explosibility in air at atmospheric pressure, 22 were capable of explosion when dispersed in the presence of an ignition source. Carbides of titanium, vanadium, zirconium and niobium gave violent explosions. Tungsten silicide and boride could not be ignited, but the carbide exploded in a test using a pyrotechnical ignitor. Molybdenum boride and silicide and the nitrides of niobium, tantalum and silicon also resisted ignition. |
