Method for continuously preparing soft agglomerated nano manganese carbonate

Abstract

The invention belongs to the technical field of nano materials and particularly relates to a method for continuously preparing soft agglomerated nano magnesium carbonate. Reagent-grade manganese sulfate and a precipitant are used as materials, preventing the reduction in the quality of finished manganese carbonate due to the introduction of impurities to the materials. A continuous feeding mode is used in the synthetic process, so that reaction is continuously carried out and production efficiency is improved. The manganese carbonate prepared herein is less than 30 nm in particle size and is strictly a nano material, the prepared manganese carbonate is spherical and is softly agglomerated, and soft agglomeration is advantageous in that agglomeration easily turns to disagglomeration in use to obtain nanoparticles of primary particle size.

Description

technical field

[0001] The invention belongs to the technical field of nanometer materials, in particular to a method for continuously preparing soft agglomerated nanometer manganese carbonate. Background technique

[0002] Manganese carbonate is the raw material for the production of electrolytic manganese metal. It can be used to manufacture magnetically permeable materials. It is one of the main components of soft ferrite. It can also be used in desulfurization catalysts, enamel pigments, varnish driers and fertilizer additives.

[0003] With the development of new energy technology, the application of manganese carbonate in the field of battery materials is becoming more and more extensive, especially the good development trend of lithium manganate battery and nickel-cobalt-manganese ternary battery, which further enhances the application value of manganese carbonate. While the application value of manganese carbonate increases, the quality requirements for the product a...
