How to solve the problem of fragile ceramic parts?

Source: https://www.innovacera.com/news/fragile-ceramic-parts.html As we all know, advanced ceramics are special material with a variety of physical properties. They as structural ceramics and functional ceramics apply in machinery, electronics, chemical industry, metallurgy, energy, aerospace and many other fields. But ceramics have an obvious disadvantage-fragility. The main reason is that the toughness of most ceramics is low, which leads to an increase in brittleness. There is a ceramic - zirconia with high toughness. It is formed by thousands of unit cells to form crystals. It then undergoes high-temperature phase transformation to form microcrystalline ceramics so that the ceramics have excellent wear resistance and drop resistance and high-temperature resistance. ZrO2 ceramic products are white. When the ceramic contains other impurities, the ceramic is grey or yellow. Commonly used moulding processes are injection and dry press. They are usually made into crucibles, mobile phon...

Silicon carbide ceramics have been widely used in high-temperature bearings, bulletproof plates, nozzles, and high-temperature corrosion resistance. Parts and electronic equipment parts in high temperature and high-frequency range. The advantages of silicon carbide are as follows: Good thermal conductivity. Not affected by corrosion; Will not melt at high temperature, no pollution to the liquid metal; Can be used to melt alloys rich in sodium and strontium; The appearance of the product will not stick to the slag, which is very simple to protect; The product has high hardness and is difficult to break; Cost-effective.

Source: https://www.innovacera.com/news/what-is-alumina-ceramic-membrane.html The ceramic membrane is an asymmetric membrane formed by inorganic ceramic materials prepared by a special process. It is divided into two types: tubular ceramic membrane and flat ceramic membrane. The ceramic membrane has high separation efficiency, good chemical stability, acid and alkali resistance, organic solvent resistance, bacteria resistance, high-temperature resistance, pollution resistance, high mechanical strength, good regeneration performance, simple separation process, low energy consumption, and long service life. Application fields: Food industry Plant (medicine) deep processing Biomedicine Fermentation Fine chemicals Characteristics of ceramic membrane materials: A coating film is required on the surface of the ceramic. The coating film is to apply a filter layer. The material used depends on the pore size,100 nm is 99.995% alpha-alumina, 50-30 nm is 99.99% zirconia, and 10 nm is...
