NOVELTY - Producing glass ceramic involves mixing 100-150 pts. wt. crushed graphene oxide powder, 10-20 pts. wt. an acrylic resin and 30-50 pts. wt. alcohol solvent. The mixture is then placed in a tube furnace in presence of an inert gas atmosphere, heated, cooled, then washed with water, and dried to obtain carbon microspheres. The obtained carbon microspheres (7-13 parts) are mixed with 3-9 pts. wt. lithium carbonate, 4-7 pts. wt. aluminum oxide, 30-55 pts. wt. Silicon dioxide, 2-7 pts. wt. stannic oxide, 1-6 pts. wt. Ruthenium oxide, 2-5 pts. wt. cobalt oxide. USE - Method for producing glass ceramic (claimed). ADVANTAGE - The method enables to produce uniform and dense glass ceramic with 395-410MPa flexural strength, 9-14 mu g/cm2 dissolution rate, and good chemical stability. DETAILED DESCRIPTION - Producing glass ceramic involves mixing 100-150 pts. wt. crushed graphene oxide powder, 10-20 pts. wt. an acrylic resin and 30-50 pts. wt. alcohol solvent. The mixture is then placed in a tube furnace in presence of an inert gas atmosphere, heated, cooled, then washed with water, and dried to obtain carbon microspheres. The obtained carbon microspheres (7-13 parts) are mixed with 3-9 pts. wt. lithium carbonate, 4-7 pts. wt. aluminum oxide, 30-55 pts. wt. Silicon dioxide, 2-7 pts. wt. stannic oxide, 1-6 pts. wt. Ruthenium oxide, 2-5 pts. wt. cobalt oxide, 3-6 pts. wt. Zirconium dioxide and 2-7 pts. wt. neodymium sesquioxide. The mixed powder is then quenched in water to melt the glass particles which are subjected to milling and cold isostatic pressing to obtain a semi-finished product which are subjected to first, second and third heating, and cooling to obtain final product.
