YDTech™ OEM of custom ZrO2 zirconia ceramics for valves, balls,bearings,rings,tubes,blocks,rollers! supplier of precision zirconium oxide ceramic balls for valves or hollow balls in china.

zro2 ball is mainly used for valve ball, full ceramic bearing, metering ball, track ball, and precision grinding ball. it can be used in fields requiring chemical resistance, high temperature, electronic insulation, magnetic insulation, non-lubrication. as valve ball, zro2 ball is now successfully used in high pressure homogenizer, diaphragm pump, metering pump, oil well pump, high prssure sprayer etc.

ceramic materials, zirconium oxide (zro2) is a material with very high resistance to crack propagation. zirconium oxide ceramics also have very high thermal expansion and are therefore often the material of choice for joining ceramic and steel.

another outstanding property combination is the very low thermal conductivity and high strength. in addition, some types of zirconium oxide ceramics can conduct oxygen ions. components made from this material are significantly more expensive than components made of alumina ceramics. zirconium oxide ceramics are used, among other applications, as tools for wire forming, as auxiliaries in welding processes, as materials for crowns and bridges in the dental industry, as insulating rings in thermal processes, and as oxygen measurement cells in lambda probes.

aluminium oxide ceramics(al2o3)roller is the the workhorse of the advanced technical ceramic tubes. it has good mechanical and electrical properties, wear resistance and corrosion resistance. it has relatively poor thermal shock resistance.

aluminium oxide ceramics(al2o3)rollers also have excellent mechanical and anti corrosion properties. calyco can supply hi-performance alumina ceramic rollers in a variety of standard sizes with the flexibility to manufacture to the customers requirements.

refractory ceramic material rollers, they provide excellent corrosion, wear and heat resistance. they improve their hardness when they are subjected to collisions. yttrium doped zirconia oxide, they provide the best properties between ceramic materials in grinding and milling applications. we have a roller made out of this ceramics. this high strength material exhibits excellent wear and corrosion properties. the material can also be for added strength and edge retention. zirconia exhibits a very low coefficient of friction and is available in mgo or yttria stabilized grades.
