This note is a report of preliminary results of x-ray examination of stone casting samples. The issue of x-ray examination of stone castings is not covered in the literature, and therefore our work represents the first attempt to use x-rays in this area. Meanwhile, with the help of x-rays, a number of problems could be solved here , such as: determination of minerals in stone casting products in the fine-crystalline phase, determination of the degree of crystallization, determination of the dispersion value of particles of the crystalline phase, etc., not to mention the transmission of castings. Our work was intended to mainly determine the minerals that arise during the crystallization of diabase smelting products at different temperatures and annealing patterns. Complexes of characteristic lines for magnetite, diopside, augite and artificial enstatite were obtained.
