There are many kinds of zirconia ceramic refractory materials, such as zirconia structural ceramics, zirconia ceramic materials, AC materials, decorative materials and so on. What are the main application areas of these ceramics? The following is introduced by Mingrui Ceramics:
zirconia ceramic structural parts
1. The zirconia crucible made of zirconia can successfully melt platinum, palladium, ruthenium, cesium and other precious metals and their alloys, and can also be used for the smelting of potassium, sodium, quartz glass, oxides and salts.
2. The zirconia fiber of zirconia refractory fiber is the only 1600c ultra-high ambient temperature with the insulation performance of ceramic fiber refractory material for long-term use, which is higher than alumina fiber, mullite fiber, and the use temperature and better aluminum silicate Fiber, high temperature stability and chemical stability, corrosion and oxidation resistance, non-volatile, no pollution.
3. Zirconia ceramic bearings have the characteristics of magnetic insulation, wear resistance, corrosion resistance, oil-free, self-lubricating, high temperature resistance, and cold resistance. Suitable for extreme environments and special working conditions.
4.Zirconium oxide grinding balls have high hardness, low wear rate and long service life, which can greatly reduce the pollution of raw materials, and can effectively ensure the quality of products. At the same time, the density of zirconia material is used as the impact energy Strong grinding media can greatly improve the grinding efficiency and effectively shorten the grinding time.
5. Zirconia ceramic knives have the characteristics of high strength, wear resistance, no oxidation, no rust, acid and alkali resistance, antistatic, and no reaction with food. At the same time, the leaves are shiny.
6. High temperature heating zirconia material as an insulating material at room temperature and a high specific resistance of 1015 ohms, it can conduct electricity when the temperature rises above 600 degrees, and 1000c is a good conductor, which can be used for high temperature heating elements of 1800c, and the maximum operating temperature can reach 2400c , Has been successfully used in the heating element 2000C oxidizing atmosphere and its equipment, the research on the electrode material of the magnetic fluid power generation is also active.
The porcelain tooth made of zirconia material does not have a metal tooth crown, has good transparency, good gloss, and more effectively avoids problems such as sensitive teeth and dark gum lines. It has good shading ability, good biocompatibility, and does not irritate the oral cavity. The mucous membrane is easy to clean. It is a high-quality porcelain tooth at home and abroad.
In recent years, with the rapid development of emerging industries such as information and communications, its products are becoming more and more high-precision, miniaturization, mechanical properties of zirconia toughened ceramics, excellent corrosion resistance, and high insulation properties. Currently in this field The ability to produce zirconia ceramic ferrules and zirconia ceramic sleeves.
Zirconia gem materials are divided into natural cubic zirconia and synthetic zirconia. Zirconia has good optical properties and is a cheap and beautiful diamond substitute.
