FIELD: metallurgy.
SUBSTANCE: as the initial components the following is used in wt %: zeolite - 20-25; acryl-silicon emulsion 0.5% or 1.5% solution of chitosan - 1-3; SiO2 - 20-25; solution of Na2SiO3 64% - 40-50; ZrOCl2 - 3-9. From the initial components the suspension is prepared and dried. Dried suspension is crushed, then screening, and fraction with particles size 0.1 mm maximum is selected, it is subjected to press forming at pressure 1.0-3.0 t/cm2. Annealing is performed at 500-600°C.
EFFECT: increased strength and separating ability in relation to substances with high molecular weight.
