Problems solved by technology

Such as high temperature and strong corrosive environment. In addition, parts made of ceramics are light in weight and have good heat insulation, which is of great significance for improving energy utilization efficiency. However, due to their internal structure, ceramic materials are brittle and sensitive to internal defects. , once the crack is generated, it often expands rapidly, causing the material to show catastrophic sudden fracture without warning. Nano-composite ceramics can be divided into three categories: inner crystal nano-composite ceramics, grain boundary nano-composite ceramics, nano-nano-composite ceramics. Composite ceramics, the first two are nano-micro composite structures, which are actually a composite material of nanoparticles reinforced micro-matrix. Due to the constraints and isolation of the matrix, the nanoparticles are not easy to grow during sintering, and the material preparation process is relatively simple. , the matrix and the second phase grains of nano-nano composite ceramics must be kept at the nanometer scale. Due to the huge activity of the nanoparticles, the grain boundary diffusion is very fast during the sintering process, which is conducive to achieving high density and is easy to occur. The grains grow rapidly, so it is very difficult to finally control the microstructure at the nanometer level

Abstract

The invention relates to the field of domestic ceramics, in particular to nanometer composite activity biological ceramic powder, which comprises 5-10 percent of nanometer yttrium, 1-5 percent of nanometer silver, 5-15 percent of nanometer zinc, 10-20 percent of iron titanium oxide, 20-35 percent of nanometer tourmaline and 25-35 percent of micron zeolite. By adding the ceramic material to all of the ceramic glazes, the produced ceramic products have the performances of air purification, rot resistance, deodorization, self-cleaning and antifouling and antibacterium; and colon bacillus and staphylococcus aureus reach larger than 99 percent. The ceramic powder can emit far infrared rays, release negative ions and play the roles of resisting bacteria, purifying, activating, keeping the pH value alkalescent, holding microcluster water and dissolving out the microelements needed by human body in improving water quality.

Description

technical field [0001] The invention relates to the field of daily-use ceramics, in particular to a nanocomposite active bioceramic powder and a processing technique. Background technique [0002] Ceramic materials have the strength similar to metal and are superior to metal in wear resistance, high temperature resistance and chemical stability, and can be used in harsh environments where general metal materials are not suitable. Such as high temperature and strong corrosive environment. In addition, parts made of ceramics are light in weight and have good heat insulation, which is of great significance for improving energy utilization efficiency. However, due to their internal structure, ceramic materials are brittle and sensitive to internal defects. , once the crack is generated, it often expands rapidly, causing the material to show catastrophic sudden fracture without warning. Nano-composite ceramics can be divided into three categories: inner crystal nano-composite cer...
