Abstract
A surface-treated ceramic powder includes a plurality of ceramic particles and a surface-treating material. Each of the ceramic particles is at least partially coated by the surface-treating material, wherein the ceramic particles have an average particle diameter ranging from 10 micrometer (μm) to 100 μm, and the surface-treating material is made of metal, metal oxide or the combination thereof.
Claims7
A metal/ceramic composite powder, comprising:
- a surface-treated ceramic powder, having a concentration ranging from 1% to 10% by weight of the metal/ceramic composite powder, and comprising:
- a plurality of ceramic particles, having an average particle diameter ranging from 1 micrometer (μm) to 100 μm, wherein each of the ceramic particles comprises a ceramic material selected from the group consisting of hydroxyapatite (HA), calcium phosphate (Ca3(PO4)2), bioactive glass (Si—Ca—Na—P—O), titanium oxide (TiO2), silicon dioxide(SiO2) and combinations thereof;
- a plurality of nanoparticles having an average particle diameter ranging from 10 (nanometer) nm to 100 nm attached on at least one of the ceramic particles;
- and
- a metal or metal oxide treating layer, at least partially coating on a surface of each of the ceramic particles with a surface coverage ranging from 40% to 99% and having a sheet resistance ranging from 104 ohms per square (Ω/S) to 1011Ω/S;
- and
- a plurality of metal particles, having a concentration ranging from 90% to 99% of by weight of the metal/ceramic composite powder and an average particle diameter ranging from 10 μm to 100 μm.
