| Popis: | The methods of quantitative phase analysis of low-absorbing powders by X-ray diffraction have been developed. The approach used accounts for the dependence of line intensity absorption factor on the Bragg angle and sample porosity and thickness. It has been shown that the use of traditional methods without reference to this dependence results in considerable errors in quantitative determination of phase content and in phase structure investigation. The application of proposed methods is illustrated by phase analysis of products of boron nitride shock compression. |
