Conclusions Heating mixtures of water solutions of potassium aluminate and kaolin and also of potassium aluminate and bentonite leads to chemical reactions in them and to the formation of a single compound in all cases, i.e., potassium aluminosilicate. The introduction of clays into the water solutions of potassium aluminate, followed by heating, leads to the formation of porous products. The mixtures of potassium aluminate and kaolin and of potassium aluminate and bentonite are coarsely porous objects with equivalent radii in the pores of 20 nm or more. Mixtures with bentonite are characterized by the presence of pores with a larger radius than mixtures containing aluminate and kaolin. By altering the sintering temperature it is possible to regulate the porous structure of these compounds. The mixtures investigated may be used for the production of porous refractory coatings and adhesive compounds for metals.
