Problems solved by technology

At present, skipping the entire field of ceramic materials, only for glazes in ceramic materials, there are relatively few studies on nanocomposite glazes, and there are even fewer reports on micro-nano composite glazes in domestic and foreign literature.

Abstract

The invention belongs to the field of ceramic glazes, in particular to micro-nano composite glazes for daily use. A micro-nano composite glaze, the glaze is composed of the following raw materials by weight: 30-60 parts of micron α-Al2O3, 4-8 parts of nano-TiO2, 9 parts of micron Ni3-9, 3-9 parts of nano-ZrO2, 50-60 parts of nano-TiC , 3‑9 parts of mullite, 20‑30 parts of kaolin, 30‑50 parts of fused corundum, 15‑30 parts of silica powder, 2‑6 parts of sodium hexametaphosphate, 3‑8 parts of zinc oxide, zirconium carbide 6‑15 parts, 3‑9 parts of silicon nitride, 3‑9 parts of yttrium carbonate, 7‑15 parts of udonite powder. The glaze prepared by the micro-nano composite glaze has high temperature resistance, wear resistance and corrosion resistance, and compared with ordinary glaze layer, it also has good toughness and strength; in addition, even if it is exposed to light for a long time, it can also be antibacterial and self-cleaning on the surface ,anti-oxidation.

Description

technical field [0001] The invention belongs to the field of ceramic glazes, in particular to micro-nano composite glazes for daily use. Background technique [0002] At present, nanocomposite ceramic materials refer to materials composed of two phases or multiphases, and at least one of them is a nanoscale raw material. At present, it is generally believed that particles with a particle size smaller than 100nm are called nanoscale particles. In the 1980s In the 1990s, someone successfully prepared Al with a strength as high as 1500MPa 2 o 3 / SiC nanocomposite ceramic materials, and the research on nanocomposite ceramic materials has become the focus of many researchers at home and abroad. [0003] However, the performance of composite ceramic materials can be improved by adding nanophases in micron-scale and sub-micron-scale matrices, which we call micro-nano composite ceramic materials. Micro-nano composite ceramic materials can not only achieve the excellent performanc...
