High precision zirconia balls are available in many sizes. Zirconia balls are most commonly used as check valves in flow control applications. When subject to stress by impact, grinding, or cracking, a zirconia ball undergoes transformation toughening which stops cracks from spreading and actually makes the ball stronger in the stressed area than what it was originally.
Silicon carbide balls are less frequently used than other ceramic materials. Due to its raw material costs and difficulty to machine. Silicon carbide offers the best heat and corrosion resistance of all the ceramic materials. Silicon Carbide is best used under low loads, low to moderate speeds and in highly corrosive environments. Used In : Ceramic Bearing & Ceramic Tube
Monel 400 and Monel 500 (often referred to as K-Monel) are Nickel base alloys used for balls in high corrosion and/or high-temperature applications. Monel balls and K-monel balls are used in non-oxidizing corrosive environments in the chemical pump, precision valves, pharmaceutical, marine, petroleum, textile, laundry, pulp, and paper industries. Monel and K-Monel balls are commonly used with seawater dilute sulfuric acid and monel and k-monel balls are highly resistant to alkaline (caustic) solutions. K-Monel balls are used where additional strength and hardness are required.
Inconel balls can be made from a variety of Inconel alloys. Inconel alloys are nickel bases with chromium and iron. Many Inconel alloys were developed for specific applications. Inconel balls can be made from these various alloys to satisfy the need for mechanical properties at high temperatures and corrosion resistance to certain chemicals often at elevated temperatures. Inconel alloys generally have excellent creep and rupture strength and high tensile and yield strengths, especially at elevated temperatures. Inconel balls are made for use in jet engine applications where high temperatures exist. Inconel balls and seats have been used by NASA on the space shuttle launch pads. Inconel balls are also made for valves and pumps and other fluid handling equipment when corrosion resistance is required
Specified for use in high-technology industries such as aerospaace and defense. Excellent corrosion resistance withstands attack from harsh chemicals and demanding environmental conditions. Light weight Silicon Nitride weighs 60% less than steel which reduces centrifugal force, skidding and wear under high speed and acceleration. High Temprature Hardness is twice that of Steel.

aluminium nitride ceramics The color of high thermal conductivity aluminum nitride ceramic sheet is gray white, and the surface is smooth. It can be made into any shape or size for easy use and installation. Aluminum nitride ceramic heat sink has a very high thermal conductivity, which is 7-10 times higher than that of aluminum oxide ceramic, and can reach 180W. Its electrical insulation performance is quite stable, its dielectric constant and dielectric loss are low, and it can withstand the ultra-high temperature of 1800 degrees Celsius without affecting the working performance of the product With the rapid development of electronic equipment, the demand for electronic or auxiliary products is also increasing, and the application rate of high thermal conductivity aluminum nitride ceramic heat sink as a matrix or packaging material is also increasing in the market.
silicon nitride ceramics Silicon nitride ceramic is an inorganic material ceramic that does not shrink during sintering. The strength of silicon nitride is very high, especially hot-pressed silicon nitride, which is one of the hardest substances in the world. It has high strength, low density, high temperature resistance and other properties. High temperature resistance, the strength can be maintained to a high temperature of 1200 without decreasing, and will not melt into a molten body after being heated, and will not decompose until 1900 It has amazing chemical corrosion resistance, and can withstand almost all inorganic acids and less than 30% caustic soda solution, as well as many organic acids; It is also a high-performance electrical insulating material. Si3N4 can be used to manufacture ball bearings by virtue of its light weight and high rigidity. It has higher accuracy than metal bearings, generates less heat, and can operate in higher temperatures and corrosive media. The steam nozzle made of S ceramic has wear resistance, heat resistance and other characteristics, and it will not be obviously damaged after being used in 650 boiler for several months.
shaft sleeve material: silicon nitride Silicon nitride shaft sleeve, wear-resistant, impact resistant, hardness higher than steel Silicon nitride (Si3N4), is an important structural ceramic material. It is a kind of superhard material, which has lubricity and wear resistance, and is atomic crystal; Oxidation resistance at high temperature. Moreover, it can resist cold and hot shock, and it will not break when heated to 1000 or more in the air, and then cooled and heated sharply. It is precisely because silicon nitride ceramics have such excellent characteristics that people often use it to manufacture mechanical components such as bearings, gas turbine blades, mechanical seal rings, permanent molds, pump bushings, etc.
Honeycomb ceramic heat storage body has many remarkable advantages, such as high temperature resistance, corrosion resistance, good thermal shock stability, high strength, large heat storage capacity, good thermal conductivity, etc., and its energy-saving effect and service life are greatly improved. Regenerative high temperature air combustion is a new combustion technology with great energy saving and environmental protection effects. Honeycomb ceramic regenerator is the key component of regenerative burner, which is widely used in various furnaces, such as heating furnaces, hot blast furnaces, heat treatment furnaces, cracking furnaces, roasters, melting furnaces, soaking pits, oil and gas boilers, etc. in steel, machinery, building materials, chemistry, petrochemical, coating, non-ferrous metal smelting and other industries. This technology makes the two regenerators alternately absorb heat and release heat through the reversing device to maximize the heat recovery of flue gas, and then heats the combustion air and gas in the furnace to more than 1000 Even the inferior fuel with low calorific value can achieve stable ignition and efficient combustion, which can save fuel up to 25% - 30%, increase the output by more than 15%, reduce the oxidation burning loss of steel billet by more than 40%, and reduce the flue gas temperature of NOx emission less than 100 ppm to less than 150 The greenhouse effect of the earth's atmosphere has been greatly reduced. If most industrial kilns in the country adopt HTAC technology, its economic and social benefits are immeasurable, which will greatly alleviate the situation of energy shortage and greatly improve the living environment of human beings.
