MODERN METHODS FOR OBTAINING SILICON NITRIDE POWDERS

The article presents the prospect of using materials based on silicon nitride in various fields of technology and a comparative analysis of the cost of raw materials for the production of tungsten hard alloys, tool materials based on silicon nitride, as well as a literature review of modern methods for producing silicon nitride powders and their properties. It is shown that at present the main methods of obtaining silicon nitride powders are self-propagating high-temperature synthesis (SHS).
