The ceramic raw material of such nanometer zirconia powder, is imported from Germany. After shaping by cold-isosactic-pressing (CIP), debinding and sinter, the rods are re-heat-treated by thermo-isostacic-pressing (HIP). Then the HIPed rods are grinded to welding pin by CNC to keep high dimension precision (with tolerance 0.002mm) and then polished by diamond to get perfect surface.(Roughness Ra<0.03um). High strength and high toughness nano zirconia ceramics are a type of advanced ceramic material that exhibits exceptional mechanical properties. Nano zirconia ceramics are primarily composed of zirconium dioxide (ZrO2) nanoparticles, which are known for their high strength and toughness. The high strength of nano zirconia ceramics is attributed to the fine grain size of the material. By reducing the grain size to the nanometer scale, the material's strength is significantly increased. This is because smaller grains…
