Налииче в составе способствует образованию кордиеритовои термостойкость структуры; котора  повышает изделий. Предмет и з о б р е т с и и   Керамическа  масса дл  химической аппаратур1 1 , включаю иа  AljO;), SiO, , СаО, Ре2Оз, NagO, LijO, Л1пО2, РгОз, от ли ч а юмехйнием , что, с целью повышени  очности и термостойкости, ОНа СОазанные окислы (в вес. %}: SiOa 20- .25 MgO0,6-10 СаО2,0-3,5 РегОз0,2-6,0 NaoO0,2-1,0 LiaO0,3-:1,5 МпОг0,05-0,1 PzOs1,5-3,0 АЬОзОсноваThe invention relates to the field of G10.: Silica and ceramic materials, and among them for chemical engineering, can be used in the limiting industry and in the CTroiiTrom. Etomileeness and etiology and CTi.ibi. mater nal. The ceramic mass of chemical equipment, incl 1Och1on1a L1 ;.Och, SiOg is known. MgO, CaO,, NagO, LiaO, MnOj and. However, the composition of the mass is not limited to one that is thermally stable and has a mechanical durability. The aim of the invention is to fix indications of flaws. This is achieved by the fact that it contains indicative windows (in weight 35-70 20-25. 0.6-10 2.0-3.5 0.2-6.0 0.2-1.0 0.3- 1.5 0.05-0.1 1.5-3.0 Alumina, clay, basalt, snodumen, etc. are used as feedstock For the core of the proposed method, the components of the mixture are milled, from s | roasting Hpit eurature 1350 1400 ° C.
