如果在某个硅氧四面体中有铝原子代替了硅原子，形成的铝硅酸根网络骨架就带

If there are aluminum atoms in a silicon-oxygen tetrahedron instead of silicon atoms, the formed aluminosilicate network skeleton will be negatively charged, so the skeleton voids have an increased ability to attract H+ and increase acidity.

If aluminum atoms are replaced by silicon atoms in a silicon-oxygen tectome, the resulting aluminum silicate root network skeleton is negatively charged, so the skeleton void attracts H-plus ability and acidity enhancement.

If there are aluminum atoms instead of silicon atoms in a silicon oxygen tetrahedron, the framework of aluminosilicate network will be negatively charged. Therefore, the ability of the framework space to attract H + is enhanced and the acidity is enhanced.<br>
