| Abstract: | The determination of true density in high purity silica powder is studied by the method of boiling and taking off gas. The test indicates the optimum conditions. The result of the sample true density determined with the method is 2.644 g.cm^-3, RSD=0.13%. The method is simple, fast and the result is satisfactory. |
