Abstract
The investigation is focused on modification of the structure 2:1 sheet silicates - illite clay by subjecting them to chemical and microbiological impact. It is shown that alkaline activation of illite clay by sodium hydroxide leads to the slight structural changes mainly characterized by water link changes. The effect of bacteria Ps. fluorescens AM PS11on structure changes of illite is small and is influenced on rheology of treated clay.It is shown that the influence of chemical treatment on porosity, bulk density and increase of compressive strength of sintered ceramic samples is notable.
研究重点是通过化学和微生物的影响对2:1硅酸盐-伊利石粘土的结构进行改性。结果表明，氢氧化钠对伊利石粘土进行碱性活化后，伊利石粘土的结构发生了轻微的变化，主要表现为水链的变化。细菌Ps. fluorescens AM ps11对伊利石结构变化的影响很小，但对处理后粘土的流变学有影响。结果表明，化学处理对烧结陶瓷试样的孔隙率、容重和抗压强度的提高有显著的影响。
