高岭石加热脫結构水后的相变問題,是国內外实驗矿物学与工艺界极为重视和久經研究的一个課題。大致可将前人的学說归納为两种不同的見解: 1.非晶貭混合物说:主张这一說法的人认为其在X-射线粉末照相中为非晶貭,就把它作为主要依据,特别是院士认为高岭石脫水后形成非晶貭Al_2O_3和SiO_2的混合物,并測得其折光率为
The problem of phase transformation after kaolinite heating and dewatering is a subject that has been paid great attention and has been studied for many times by experimental mineralogy and process at home and abroad. Generally, the theory of the predecessors can be summed up in two different opinions: 1. The amorphous mixture says: The proponents of this claim regard it as amorphous in X-ray powder photography and regard it as the predominant Based on, in particular, the academicians believe that kaolinite dehydrated to form a mixture of amorphous Al 2 O 3 and SiO 2, and measured the refractive index of
