| 中文摘要: |
| 本方法仅适用于河北某地含刚玉的矽线石中铝的物相分析。主要根据矽线石(Al2O3·SiO2)中,先测出SiO2的结果再由全Al2O3减去矽线石中Al2O3,即可得出刚玉的结果。 |
| 英文摘要: |
| This method is suitable for sillimanite containing corundum in certain deposit of Hebel province. Firstly, alumino-silicates such as orthoclase, sericite, biotite and orthochlorite are dissolved by HF-HCL-HNO3 at room temperature. Then the residues are melted by mixed flux of H3BO3-Na2CO3-K2CO3 at 1140-1160℃ in order to get sillimanite and corundum. The SiO2 and Al2O3 are determined by HCl dipping method. According to the compositions of sillimanite( Al2O3·Si2O3), the totle Al2O3 can be calculated by SiO2 and Al2O3 in corundum is got from the difference between totle Al2O3 and Al2O3 in sillimanite. |
