NOVELTY - A magnesium yellow feldspar bone support preparing method involves weighing graphene, boron nitride nanotubes (BNNT) and magnesite feldspar powder, stirring in absolute ethanol to obtain graphene suspension, BNNT suspension and magnesium yellow feldspar suspension. The graphene suspension is poured into the BNNT suspension and stirred. The magnesium feldspar suspension is added to the graphene/BNNT suspension, stirred, filtered and vacuum dried to obtain powder. The powder is subjected for selective laser sintering process to obtain the finished product. USE - Method for preparing magnesium yellow feldspar bone support. ADVANTAGE - The method enables preparing magnesium yellow feldspar bone support with excellent mechanical property, large specific surface area, improved strength and toughness, and improved osteogenesis ability. DETAILED DESCRIPTION - A magnesium yellow feldspar bone support preparing method involves weighing graphene, boron nitride nanotubes (BNNT) and magnesite feldspar powder, stirring in absolute ethanol to obtain graphene suspension, BNNT suspension and magnesium yellow feldspar suspension. The graphene suspension is slowly poured into the BNNT suspension and stirred ultrasonically to obtain a graphene/BNNT suspension. The magnesium feldspar suspension is slowly added to the graphene/BNNT suspension and stirred to obtain a graphene/BNNT/magnesium yellow feldspar suspension. The graphene/BNNT/magnesium yellow feldspar suspension is filtered and vacuum dried to obtain a uniformly dispersed mixed powder. The uniformly dispersed mixed powder is subjected for selective laser sintering process to obtain the finished product.
