Calcium polyphosphate/wollastonite bio-composite ceramic material and preparation method therefor
Disclosed are a calcium polyphosphate/wollastonite bio-composite ceramic material and a preparation method therefor. The composite ceramic material is made of calcium polyphosphate and wollastonite, and the content of the calcium polyphosphate in mass percentage is 5%-90%; preferably 35%-70%, further preferably 50%-70%, still further preferably 50%, 60% or 70%, and most preferably 50%. A calcium polyphosphate precursor is prepared from calcium dihydrogen phosphate as a raw material by means of a water washing and drying-sintering method. A calcium polyphosphate/wollastonite bio-composite ceramic material is successfully prepared by mixing and sintering the two, and the structure, mechanical properties, biological activity and degradation properties thereof may be adjusted by means of the adjustment of the proportional relationship between the two, thereby preparing a biomaterial with suitable properties according to actual requirements.
