内容記述 | We have studied on metallurgy of beryllium (the pile material) by reducing beryllium oxide with calcium. We produced beryllium-calcium alloy, and then extracted metallic beryllium from beryllium-calcium alloy. And we obtained the following results; A. Beryllium-calcium alloy production. 1. Every mixing method may be used in this case. 2. The optimum conditions were Reaction temperature; > 1,200℃ Reaction time; > 5 hrs. Mixing weight-ratio of calcium to beryllium oxide; > 6 In this case the yield percentage of beryllium was one hundred percent. B. Extraction of beryllium 3. Ammonium chloride cold solution process was better than high temperature vacuum process. 4. Metallic beryllium powders (produced by ammonium chloride process) were chemically pure and they had spectrographical traces of iron, aluminium, magnesium and calcium. This smelting process is very useful, and has one hundred percentage utilization of beryllium oxide, and the produced metallic powders are convenient in beryllium powder metallurgy. |
