Preparation of Nano-hexagonal Plate Mg-Al Water Talc Crystal Through Co-precipitation
Abstract：The study is set on the preparation of magnesium aluminates water talc with co-precipitation method, focusing on the influence of raw material concentration and reaction temperature parameters on nanocrystalline. The methods of scanning electron microscope （TEM）, X-ray Diffract（XRD） meter and other methods were used to characterize Nanocrystalline. The results show that pure phase structure of the nana magnesium hex flake aluminum water talc crystals can be prepared with the use of co-precipitation. The best preparation conditions are： NaOH concentration over 0. 625 mol/L, reaction temperature 90 ℃ , Na2CO3 concentration of 0.09 mol/L. The yield of magnesium aluminates water talc will reach a maximumof 95%.
