Benefits of technology

This patented technology provides new types of mineralized tissue that can be used as effective medical devices or dental fillers due to their ability to promote rapid healing without causing inflammations caused by metal ion exposure. These compositions include CaFeP2O4 with added Fe3+ while adding other metals like selenium (Se) instead of chromium(Cr). They may contain different forms such as crystalline powders, flakes, wires, etc., depending on how they were made beforehand. Overall these technical improvements make them better than existing products from traditional sources.

Problems solved by technology

This patents describes different types of biomedial materials such as metal-ceramics like CPC and TCP due to their unique characteristics. However, there exist challenges related to finding suitable alternatives without compromising on certain technical features associated with these materials' applications.

Abstract

The invention discloses a calcium phosphate iron bioceramic and a preparation method thereof, and relates to the field of biomaterials. The bioceramic is prepared from the following ingredients in parts by weight: 50-70 parts of tertiary calcium phosphate, 12-20 parts of iron oxide, 4-8 parts of nano tin oxide, 10-18 parts of ferric sulfate, 6-12 parts of calcium hydrophosphate and 2-5 parts of magnesium oxide. The preparation method comprises the following steps: (1) weighing; (2) ball milling; (3) cold press molding; (4) high-temperature calcining; (5) cooling. The bioceramic has the function of promoting bone growth, and can slowly release the elements of calcium, phosphorus and iron in the process of implanting the human body; and besides, the mechanical property is improved, and the bioceramic is an ideal bone substitute and renovating material.
