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;<br/>A. Beryllium-calcium alloy production.<br/>1. Every mixing method may be used in this case.<br/>2. The optimum conditions were<br/>Reaction temperature; > 1,200℃<br/>Reaction time; > 5 hrs.<br/>Mixing weight-ratio of calcium to beryllium oxide; > 6<br/>In this case the yield percentage of beryllium was one hundred percent.<br/>B. Extraction of beryllium<br/>3. Ammonium chloride cold solution process was better than high temperature vacuum process.<br/>4. Metallic beryllium powders (produced by ammonium chloride process) were chemically pure and they had spectrographical traces of iron, aluminium, magnesium and calcium.<br/>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. | |||||
