High Temperature Resistance Zirconia Ceramic Parts Stirring Rods
Product features :
1.Excellent electrical insulation
2. High dimensional tolerances
3. Chemical corrosion resistance
4. Good thermal shock properties and can withstand temperatures up to 1700o C.
5. High temperature resistance
Application : used in high-temperature applications that require erosion resistance and electrical or thermal insulation, like Insulator Ceramic Rods, Semiconductor applications, High voltage requirements, Wire guide etc
With the advantages of high insulation strength, fireproof and high temperature resistance, compact volume, seismic resistance and high mechanical strength, our products include ceramic plunger, stirring rod, sealing ring , precise ball, standard block, straining ratchet, braid plate, wear ring, guide pulley, ceramic valve for petroleum, chemical industry and pipeline. All the ceramics can be customized.
Quality assurance:
Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance,but relatively low strength and fracture toughness.Alumina ceramics are generally white but may also be pink or ivory.The color is derived from either the sintering additives or impurities in the raw materials.
