Abstract
Prezenta inventie se refera la o masa ceramica poroasa pe baza de bazalt. Masa ceramica, conform inventiei, are o compozitie de 53,2% SiO2, 14,11% Al2O3, 4,55% Na2O, 6,18% CaO, 4,23% MgO, 3,68% Fe2O3 si 2,38% K2O. Prin utilizarea bazaltului macinat care se amesteca în proportie 84...86% cu o solutie de silicat de sodiu cu densitatea 1420 kg/m3, se obtine o masa care se granuleaza si în faza de presare se utilizeaza o pulbere având urmatoarea distributie granulometrica: 5% 500...800 niu, 90% 250...500 niu, 5% 250 niu, ceea ce asigura obtinerea unor produse ceramice cu porozitate controlata.
