Beschreibung
Zusammenfassung:	FIELD: oil and gas production. ^ SUBSTANCE: method comprises successive grinding, granulation, and baking at 1215-1290 of ceramic material, particularly magnesium metasilicate and/or calcium metasilicate. Grinding is conducted until fraction below 0.01 mm is obtained and granulation gives fraction 0.2-1.8 mm. Ground metasilicate, prior to be granulated, is mixed with modifying and caking additives, e.g. titanium oxide, zirconium silicate, iron oxide, clay, and the like. ^ EFFECT: improved performance characteristics of disjoining members. ^ 1 tbl, 3 ex
