Aim: To enable the participants to identify pure substances and mixtures of few components using X-ray powder methods, and to familiarize the participants with the use of the polarizing microscope for identifying crystalline substances in transmitted light. The course has been organised with the aim of using these methods for control of raw materials and the solution of other material problems in industry.
|
|
Contents: The course is split into two parts of equal length. One part covers powder diffractometry using a Philips diffractometer and the Debye-Scherrer and Gandolfi methods. Identification of pure substances and mixtures using a reference work, identification indices for X-ray reflections and calculation of cell constants of simple substances. The other part of the course deals with the use of the polarisation microscope. Determination of optical properties of solids in transmitted light, such as pleochroism, refraction and double refraction for fast identification of crystalline substances.
