| titleOfInvention | A kind of preparation method of high specific surface area hexagonal boron nitride microsphere particle and its block |
| abstract | The present invention relates to a preparation method of high specific surface area hexagonal boron nitride microsphere particles and blocks thereof. The preparation method comprises the following steps: mixing block copolymer type surfactant, polar solvent, triazine nitrogen-containing The heterocyclic organic matter and the aqueous solution containing the aldehyde group molecule are fully reacted to form a clear and transparent mixed solution A; the boron source chemical reagent containing the B-O component is dissolved in the clear and transparent mixed solution A, and stirred and mixed until a clear and transparent viscous solution is obtained. thick colloidal solution, and then let the clear and transparent viscous colloidal solution stand to make it fully polymerize and solidify to form a hard block, and obtain the block precursor B assembled from the polymer-type microsphere particle precursor; The hexagonal boron nitride microsphere particle product D and its bulk product C are obtained by the high temperature pyrolysis of the precursor B. Hexagonal boron nitride microspheres have the advantages of flexible and adjustable spherical diameter, uniform morphology, high specific surface area, high purity and good agglomeration. |
