Abstract
The invention relates to a preparation method of graphene-reinforced magnesium porcelain for daily use. The mass ratio of graphite to carbon nanotubes to magnesium porcelain blank in the magnesium porcelain for daily use is (0.3-0.5):(0.1-0.5):(99-99.7), the graphite and the carbon nanotubes serve as a tough phase, the magnesium porcelain for daily use serves as a base body, and the graphene-reinforced magnesium porcelain for daily use is prepared after high-temperature sintering through an ultrasonic and ball milling combined preparation technology. Equipment is simple, the cost is low, the preparation technology is stable, dispersion of the tough phase in the graphene-reinforced magnesium porcelain for daily use is uniform, mechanical properties are excellent, the breaking strength and fracture toughness reach 187-205 Mpa and 1.90-2.2 Mpa m1 / 2 respectively and are increased by 50-75% and 62-120% respectively compared with common magnesium porcelain for daily use, and application prospects are good.
Description
technical field [0001] The invention belongs to the technical field of daily-use ceramic materials, and in particular relates to a preparation method of graphene-reinforced magnesia daily-use porcelain. Background technique [0002] Magnesia porcelain has the advantages of high mechanical strength, delicate and white porcelain, and good light transmission. Magnesia daily-use porcelain tableware and tea sets have a special flavor compared with traditional porcelain, and are very popular in domestic and foreign markets. However, the disadvantages of magnesia porcelain, such as fragility, brittleness and poor fracture toughness, restrict the transportation and use of magnesia porcelain. [0003] Graphene and carbon nanotubes are excellent one-dimensional and two-dimensional carbon materials, which respectively reflect one-dimensional and two-dimensional anisotropy. When graphene and carbon nanotubes are combined with other materials to form a three-dimensional network structure...
