Abstract

We have used chemical and x-ray analysis to study the stability and phase composition of silicon nitride powders with different panicle size ranges and morphology in biochemical media (physiological solution, gastric juice, blood serum) at 37°C. We have established the high solubility of Si3N4 in physiological solution and blood serum. The solubility increases with the dispersity of the powder in all the media. We explain this behavior of silicon nitride in biochemical media using modern theories of bioinorganic catalysis.
