Abstract
The invention provides a method for preparing a magnesium oxide nano powder material, comprising the following specific steps: adding polyvinyl alcohol aqueous solution of concentration 3 wt% into magnesium hydroxide solid at a ratio of 0.5-0.8L/kg, and uniformly mixing; adding oxalic acid dihydrate solid with equal matter of as magnesium hydroxide; grinding for 20-30 min, and drying the mixture at 70-100 DEG C; calcinating the mixture to a temperature in a range of 650-750 DEG C and keeping for 1-2 h. The obtained magnesium oxide particles are spherical, with particle size of 10-20 nm and uniform granularity.
Description
Technical field:
The present invention relates to a kind of Preparation of Nanoscale MgO Powders method, belong to the nano material preparation technical field.
Background technology:
The bitter earth nano powder body material is a kind of novel high function fine inorganic material; Because the singularity of its structure; Determined it to have the properties such as optics, calorifics, electricity, mechanics and chemistry that are different from body, be widely used in fields such as electronics, catalysis, potteries.The bitter earth nano powder body material has high firmness and HMP, can be used to make refractory materials and sintering metal etc.The bitter earth nano powder body material also can be used as the filler of paint, paper and makeup, the weighting agent of plastics and rubber and strengthening agent, the dispersion agent of fat and the subsidiary material of various electronic materials etc.
The nano-powder material industrialized producing technology requires the preparation method simple, and production cost is suitable, and repeatability is constant, and powder granularity is even, and product purity is high, and the reunion degree is low.For this reason, many investigators have inquired into multiple Preparation of Nanoscale MgO Powders method, and wherein great majority all are as presoma with Marinco H.Because produce in the process of bitter earth nano powder body material as presoma with Marinco H, the washing water consumption of the cotton-shaped Marinco H that is settled out is time-consuming, and the bitter earth nano particle aggregation after the roasting is more serious.It is higher to seek production efficiency, and the better bitter earth nano powder body material of quality product working method is one of focus of research always.
Summary of the invention
The present invention is a raw material with solid hydrogen Natural manganese dioxide, is precursor with the magnesium oxalate, prepares granularity tiny and uniform bitter earth nano powder body material.Concrete operations of the present invention are following: add 3wt% Z 150PH (PVA 17-92) aqueous solution 0.5-0.8 liter according to per kilogram Marinco H solid and stir; Add two oxalic acid hydrate solids again with amount of substances such as Marinco H; Ground 20-30 minute; 70-100 ℃ of drying, roasting is to 650-750 ℃ and constant temperature 1-2 hour.The magnesia particle pattern that generates is spherical, particle diameter 10-20 nanometer, epigranular.
