Ceramic Products

Ceramic products developed by SunYoung Industry include Ceramic Balls, Ceramic Rings (For pad-printer), and other Advanced Ceramic Parts:1. Ceramic balls have the following features: 1) Materials: silicon nitride (Si3N4), Zirconia (ZrO2), Alumina (Al2O3) 2) Application: for bearings, inspection, pumps, and other rolling conditions 3) Capacity: 3,000,000pcs/month for 5/32" silicon nitride balls 4) Diameter: 1/64" ~ 2" 5) Precision: G3 ~ G20 Specifications (compare to steel): 1) Lighter than steel; 2) Larger elastic modulus; 3) Lower friction coefficient, rolls more freely; 4) Lower coefficient of thermal expansion; 5) Superior surface finish; 6) Higher high-temperature hardness; 7) Never rust, and can roll without oil or grease; 8) Better corrosion resistant than steel2. Ceramic rings (for pad-printer) have the following features: 1) Material: zirconia (ZrO2) 2) Have fine crystalline and density higher than 6.05g/cm3 3) Have superior wear resistance performance, which lengthens the life of the ceramic ring and avoids leakage 4) Edge breadth can be less than 0.1mm, single or double edge with different specifications, thickness can be less than 3mm3. Advanced ceramics provides the perfect solution and a cost-effective, high performance alternative to traditional materials such as metals, plastics and glass. In general terms, advanced ceramics exhibits exceptional properties that make them highly resistant to melting, bending, stretching, corrosion or wear. Their hardness, physical stability, extreme heat resistance, chemical inertness, biocompatibility, superior electrical properties and, not least, their suitability for use in mass produced products make them one of the most versatile groups of materials in the world. SunYoung Industry can also supply with ceramic parts, which are made of alumina, zirconia, silicon nitride, silicon carbide, etc., to customers operating in the petrolic, chemical, mechanical, automotive, textile, military, medical, aerospace, semiconductor, telecommunications, thermal management, domestic product and processing equipment industries. 1) Alumina (Al2O3) is the most widely used advanced ceramic material. It offers very good performance in terms of wear resistance, corrosion resistance and strength at a reasonable price. Its high dielectric properties are beneficial in electronic products. 2) Zirconia (ZrO2) has the highest strength and toughness at room temperature of all the advanced ceramic materials. The fine grain size allows for extremely smooth surfaces and sharp edges. 3) Silicon nitride (Si3N4) exceeds other ceramic materials in thermal shock resistance. It also offers an excellent combination of low density, high strength, low thermal expansion and good corrosion resistance and fracture toughness. 4) Silicon carbide (SiC) has the highest corrosion resistance of all the advanced ceramic materials. It also retains its strength at temperatures as high as 1400C and offers excellent wear resistance and thermal shock resistance.
