Abstract
The invention relates to a preparation method of magnesium oxide, particularly a preparation method of flower-like magnesium oxide. The method comprises the following steps: mixing 0.01-0.09mol of magnesium chloride powder and 0.1-0.2mol of urea powder; adding a certain amount of deionized water; adding a pH value regulator to regulate the pH value to 6-7; adding the solution into a reaction kettle, and carrying out hydrothermal reaction at 180-200 DEG C for 10-24 hours; and carrying out calcining after-treatment to finally obtain the flower-like magnesium oxide product. The pH value regulator is a hydrochloric acid solution or hydrogen peroxide solution. The one-step hydrothermal process is utilized to prepare the special-shaped flower-like magnesium oxide product.
Description
Technical field
The present invention relates to a kind of magnesian preparation method, relate in particular to a kind of flower-shaped magnesian preparation method.
Background technology
The physicals of inorganic materials and pattern have very large contacting, so the synthetic concern that is more and more subject to people of special appearance.Especially magnesium oxide, as the application of wide band conduction body, becomes one of emphasis of inorganic salt pattern research.But the preparation method of magnesia imperfection of floriform appearance, causes its pattern irregular at present.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of flower-shaped magnesian preparation method is provided.Can obtain the flower-shaped magnesium oxide of pattern homogeneous.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of flower-shaped magnesian preparation method, it is characterized in that, and comprise the following steps: the magnesium chloride powder of 0.01mol-0.09mol is mixed with the urea powder of 0.1mol-0.2mol; Add again a certain amount of deionized water; Add again pH value conditioning agent to make pH value between 6-7; Again this solution is put into reactor and carry out hydro-thermal reaction, reaction times 10-24h, temperature of reaction 180-200 ℃; After calcining aftertreatment, finally obtain flower-shaped magnesium oxide product again.
Described pH value conditioning agent is hydrochloric acid soln, superoxol.
The invention has the beneficial effects as follows: the magnesium oxide product of preparing flower-shaped this special appearance by one step hydro thermal method.
Embodiment
Below principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
Preparing flower-shaped magnesian better implementation step is: the magnesium chloride powder of 0.04mol is mixed with the urea powder of 0.1mol; Add again a certain amount of deionized water; Add again hydrochloric acid soln, the continuous condition pH of superoxol, make pH value till 6.5; Again this solution is put into reactor and carry out hydro-thermal reaction, 180 ℃ of reaction times 24h, temperature of reaction; After calcining aftertreatment, finally obtain flower-shaped magnesium oxide product again.
Claims (2)
