Equally have the shortcomings that Preparation equipment complexity, be not easy to promote, energy consumption cost it is high.In contrast, liquid phase method have equipment it is simple, at
The advantages that this is low, easy to operate, is current industrial circle, especially the primary selection of laboratory preparation.And solid phase method equipment, work
Skill is relatively easy, but product quality purity is not high, is easily contaminated, and is mainly suitable for certain couples of TiO2Appearance and size requires not
Stringent application.The one kind of hydro-thermal method as liquid phase method dissolves indissoluble or insoluble substance simultaneously by the environment of high temperature and pressure
And recrystallize, realize the formation and modification of inorganic compound, can not only prepare one pack system tiny crystals, but can prepare bi-component or
Multi-component special compound powder can not only carry out impossible reaction under room temperature but also can overcome certain high-temperature process that can not keep away
The hard aggregation etc. exempted from.
