Study and application of anti-caking method for powdered MAP produced by pressure neutralizing-spraying autothermal process;
加压中和—喷雾自热法干燥粉状磷酸一铵抗结块方法的研究与应用
Before and after the process of heating to grahitization temperature 2770K, the structure of powdered graphite treated with acid and acid base was analysed by X ray diffraction line profile method.
采用X射线线形分析方法对经过两种不同化学方法和石墨化温度 (2 770K)处理的 4个粉状石墨 (1# 至 4# )试样进行了分析计算 ,计算结果显示这 4个粉状石墨试样的晶粒尺寸基本保持不变 ,微观应变增加 ,位错密度减小。
From the measurements of chemical analysis and X-ray diffraction of KRG W1 powdered graphite, it is found that this graphite has not only a high degree of graphitization and a fixed carbon content of up to 99 99%, but also contains a certain quantity of rhombohedral graphite.
借助化学分析法和X射线衍射仪对KRG W1型粉状石墨进行测试 ,发现这种石墨不但石墨化度高而且固定碳高达 99。
