Abstract: The solubility of some inorganic materials was studied. It was found that Ca dissolution was high in calcium phosphates with Ca/P ratios 1.67-2.0. Dissolution of P was moderate compared with dissolution of Ca. The composites, HA content 70 wt-%, and HA showed to be corrosion resistant. Dissolution of alumina in the mineral muscovite, used as a filler material, was found to be neglectable and dependent on the density of the composite.
