Intensification of sintering for low-melting clays upon variation of the firing atmosphere parameters

It is shown that when a reduced pressure is created in the firing zone due to the released gases (Н ₂ and CO), the nature of the gaseous medium becomes reductive, which contributes to an earlier reduction of active forms of iron oxides and the formation of a glass phase, intensifying the sintering of clay rocks. ...
