    2020-12-14 · The release of nitrogen and silicon is the chemical origin of Si 3 N 4 ’s biological effectiveness. A hydrolysis process initiates the protonation of amino groups at the Si 3 N 4 surface. The electrophilicity at the adjacent silicon sites increases, which in turn leads to the propensity of these sites to undergo nucleophilic attack by water.

    Aluminium is the third most abundant element in the Earth’s crust with oxygen and silicon being the first and second. The respective percentages are 50, 26 and 7.5 (Williams & Fraústo da Silva, 1996). It is therefore not surprising that soils and weathered rocks constitute the major sources of aluminium in environmental media (Bowen, 1979).
