Method for preparing magnesium metatitanate nano-powder by chemical coprecipitation method
The invention relates to a method for preparing magnesium metatitanate nano-powder by a chemical coprecipitation method, and belongs to the technical field of microwave dielectric ceramic powder synthesis. The method can be used for preparing spherical magnesium metatitanate nano-powder with uniform chemical composition, uniform particle size, single crystal phase and good development at a low calcination temperature of 700-1000 DEG C and a short calcination time of 2-4 hours. The preparation method is low in alkali concentration, low in calcination temperature, short in calcination time, simple in technological process, low in cost, small in pollution and uniform in component, and the prepared magnesium metatitanate is high in sphericity degree and good in dispersion, can be used for preparing high-performance microwave dielectric ceramics and has wide application prospects in the field of microelectronic devices.
