Electrical Insulation Small Ceramic Needle Pin with Good Roughness
Features of Small Ceramic Needle pin :
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
Refractory Zirconia Ceramic Rod / Rod Ceramic High Hardness
Small Ceramic Needle pin can be divided into two major divisions—traditional and advanced. The origins of traditional ceramics date back more than 26 centuries. Modern applications include both consumer and industrial products, including dinnerware, tile, abrasives for grinding or lapping and those fanciful figurines made by hobbyists at local community centers. Advanced ceramics have roots extending to the early
1. Small Ceramic Needle pin 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.
2. Excellent thermal insulation/low thermal conductivity (2.5 to 3 W/mK),
3. Very high resistance to crack propagation, high fracture toughness (6.5 to 8 MPam1/2).
Industrial Small Ceramic Needle pinIntriduction
Small Ceramic Needle pin is the most widely applied and cost effective technical ceramic material. It offers a combination of superior mechanical strength and electrical properties, wear resistance and corrosion resistance. The maximum working temperature is up to 1700 °C with relatively high thermal conductivity. It is also an electrically insulating material with a high electrical resistivity. The good corrosion resistance makes it insoluble in water and slightly soluble in strong acid and alkaline solution.
