Embodiment

[0023] (1) The ka-nepheline powder used in this patent is obtained by hydrothermal treatment with the ko-nepheline powder as a raw material. Crystallographic diffraction analysis such as figure 1 . Index calculation is carried out on the X-ray powder crystal diffraction data of raw materials, and the lattice constant is basically consistent with the standard value of hexagonal kacryptite in the standard JCPDS card (card number 85-1413) (Table 2).

Abstract

The invention relates to a method for synthesizing potassium nitrate as a by-product of nanometer kaolinite with kaliophilite powder bodies, and belongs to the field of preparation of fine chemical materials. The technology comprises the following steps: mixing the kaliophilite powder bodies with a nitric acid solution, performing a hydrothermal reaction under the condition of 210-250 DEG C for 12-36 hours, and performing synthesis so as to obtain a solid phase product, namely the nanometer kaolinite, and a liquid phase product, namely a potassium nitrate solution. According to the method disclosed by the invention, the kaliophilite powder bodies and the nitric acid are used as raw materials, the nanometer kaolinite and the by-product namely the potassium nitrate are synthesized, and components of potassium, aluminum and silicon in kaliophilite are fully utilized, so that the technology of the whole process is simple, modern industrial requirements of 100% resource utilization rate, zero discharge of waste gas, waste water and industrial residues, high efficiency, energy conservation and clean production can be met, and industrialized production is easy to realize.

Description

technical field [0001] The invention belongs to the technical field of preparation of fine chemical materials, and in particular relates to a method for synthesizing nano-kaolinite by-product potassium nitrate by using kalnite powder. Background technique [0002] Kaolinite is a 1:1 layered silicate. Nano-kaolinite can be used as a filler for rubber and plastics and a flame retardant synergist. It can not only improve the tensile strength of the material, but also improve the gas barrier of the material. performance; in the field of ceramics, ceramics made of nano-kaolinite have high hardness, high toughness and good ductility; in terms of coatings, nano-kaolinite can improve the adsorption, stability, dirt resistance and fading resistance of coatings Significantly strengthened, it can also show some special optical effects and so on. Due to the surface effect, small size effect, quantum size effect and macroscopic quantum tunneling effect of nano-kaolinite, and its new cha...
