FIELD: chemistry.
SUBSTANCE: invention relates to production of refractory articles for lining thermal generating units. The dinas refractory is obtained from a mixture which contains a siliceous aggregate, a mineralising additive based on calcium oxide in form of lime milk and a temporary binder in form of liquid industrial lignosulphanate. The siliceous aggregate used is quartz glass with particle size of 0-3 mm with SiO2 content of less than 99.0% and magnetised quartzite with particle size of 0-0.09 mm, with the following ratio of components, wt %: magnetised quartzite with particle size of 0-0.09 mm - 22-34; mineralising additive (based on CaO) - 1.8-3.3; temporary binder (dry more than 100%) - 2.0-4.0; said quartz glass with particle size of 0-3 mm - the balance.
EFFECT: improved composition of refractory articles.
