FIELD: claydite production. SUBSTANCE: method involves addition of corrective additive - herbicide diphenylamide at concentration 0.5-2 wt.-% (as active substance) to the clay raw following by granulation, drying and calcination of granules following by cooling. Claydite properties: filled mass after addition of 1 wt.-% additive is 380 kg/m3, compression strength at 2.15 MPa in the presence of 2 wt.-% additive is 335 kg/m3 and 1.8 MPa, respectively. EFFECT: improved method of claydite preparing. 1 tbl
