A method of preparing for nano -magnesium oxide

The present invention involves a preparation method of magnesium oxide nano crystal, which belongs to the field of nano -material preparation technology. The purpose is to provide a high -quality, low -cost, low energy consumption, ultra -fine nanocarium oxide preparation.Add the surfactant, use sodium oxalate as the sediment, the reactive solution reacts the water and heat in the high -pressure kettle for a period of time. Take out the front -drive body to precipitate the centrifugal and wash the vacuum temperature and dry it.Make magnesium nano -crystals.The particle size of magnesium oxide nanocrystals made through the above method is narrow, the crystallization is high, the particle size is between 5 and 10nm, and the yield is more than 90%.

A preparation method of nano -magnesium oxide, which is characterized by dissolving soluble magnesium salt through water, adds the surfactant, and then adds a precipitant. Mixes evenly.~ 80%, heating, the temperature should be controlled between 100 ° C and 180 ° C, so that the water heating reaction occurs. After the reaction is over, take out the front -drive body to precipitate.The burning process is divided into two steps, the first step: burning for 1 to 2 hours between 350 ° C and 450 ° C; the second step: the temperature to 600 ° C to 650 ° C for 1 to 2 hours, that is, nano magnesium oxide.
