The composition of sodium aluminate solution is very complicated, which contains carbonates, sulphates and so on.

由于铝酸钠溶液成分十分复杂，含有碳酸盐、硫酸盐等多种杂质，在蒸发过程中会以盐类结晶形式析出而附着在换热管壁上形成结疤，进而影响蒸发器的效率和运转率。

Spinel is a compound of magnesia and alumina(Al2O3) and is thus a magnesium aluminate(MgAl2O4), found as accessories in igneous rocks, in metamorphosed aluminous schists, in contact metamorphosed limestones and sometimes in high temperature iore veins.

尖晶石主要成分是氧化镁和氧化铝，结晶习性是等轴晶系漂亮的正八面体。镁被铁置换就是铁尖晶石，被锌置换就是锌尖晶石，铁完全置换镁形成磁铁矿，铬置换铁尖晶石形成铬铁矿，这些类质同相的等轴晶系都是八面体结晶的尖晶石族矿物。
