An experiment on transformation of biotite (fraction <1 μm) particles placed into containers with different permeability in the AEL horizon of podzolic soil was performed in order to estimate the contribution of different factors to the transformation of biotite in the modern soil. After two-year-long incubation in the AEL horizon, biotite was transformed into vermiculite, mixed-layer biotite–vermiculite,...
A batch composition was developed for producing facing ceramic based on low-plastic clay. Titanium dioxide (10 wt.%), boric acid (5 wt.%), and galvanic slurry (to 5 wt.%) are introduced into the batch as additives. The influence of the batch components on the composition and structure of the developed material as well as the basic operating properties of the articles obtained on the basis of the new...
