NOVELTY - Preparing a nanoceramic material involves weighing 30-50 pts. wt. titanium nitride, 30-40 pts. wt. iron silicide, 10-20 pts. wt. titanium silicide, 3-8 pts. wt. graphene, 2-6 pts. wt. ferric citrate, 45-55 pts. wt. zirconium dioxide, 4-8 pts. wt. magnetic hematite powder, 60-65 pts. wt. polybutylene terephthalate (PBT), 6-8 pts. wt. nano boron fiber, 4-8 pts. wt. alumina, 2-6 pts. wt. potassium sulfate, 3-11 pts. wt. nano zinc oxide, 2-4 pts. wt. alkylphenol ethoxylate, 3-5 pts. wt. aluminum nitride, 3-7 pts. wt. sodium hydroxide and 3-5 pts. wt. oleic acid, putting each raw material into a high-speed mixer, and mixing and stirring to obtain mixed material. The uniformly mixed material is placed in a mold for pressing into a preform at a pressing pressure of 40-50 Megapascal (MPa). The preform is sintered at a high temperature of 900-1200 degrees C for 3-6 hours, and then cooled to room temperature to obtain final product. USE - Method for preparing nanoceramic material for dental restoration. ADVANTAGE - The method enables to prepare nanoceramic material, which has good mechanical properties, good air permeability, strong chemical stability, excellent biocompatibility, and extremely high fidelity.
