| description | FIELD: nuclear power engineering; confining molten core in water-cooled tank reactors. SUBSTANCE: method includes preparation of charge by milling and mixing up components and producing molding powder from charge. This molding powder is molded and formed in briquettes which are calcined in air environment at 1300- 1380 C for 2-14 h. Then briquettes are crushed, powder is milled and sized to fractions and mixed up with binder, parts are molded and calcined at 1200-1300 C for 4-14 h. Silicon dioxide and part of alumina are introduced in charge in the form of kaolin whose content is higher than desired content of silicon dioxide in material by 2.1-2.3 times. EFFECT: enhanced reproducibility of physical and mechanical properties of molten-core sacrificial ceramic materials. 5 cl, 1 tbl, 9 ex |
