Hydroxyapatite whisker reinforced glass ceramic dish and preparation method thereof
The invention discloses a hydroxyapatite whisker reinforced glass ceramic dish and a preparation method thereof. The hydroxyapatite whisker reinforced glass ceramic dish is prepared from the following raw materials in parts by weight: 20-30 parts of broken glass, 5-10 parts of hydroxyapatite whisker, 12-18 parts of basalt, 10-15 parts of hornblende, 4-7 parts of violaceous halite, 2-4 parts of coal powder, 8-14 parts of analcite, 5-10 parts of goldstone, 10-15 parts of limestone, 2-3 parts of manganese sulfate, 4-6 parts of barium metaphosphate and 6-8 parts of auxiliary agent. In the invention, the hydroxyapatite whisker is composited with glass ceramic matrixes, so that a very good strength and toughness enhancing effect is achieved, and the mechanical property of the glass ceramic dish is greatly improved. The breaking strength of the prepared glass ceramic dish is greater than or equal to 400 MPa, and the fracture toughness is greater than or equal to 4.5 MPa.m1/2. Fracture during use of the glass ceramic dish is significantly reduced, and the service life of the glass ceramic dish is prolonged.
