Dissolution and reprecipitation in porous solids

Research output: Contribution to journalArticlepeer-review

When a porous solid dissolves in acid, the dissolved solid can diffuse both into the bulk solution and into the solid's pores. In some cases, these dissolved species can precipitate in the pores, making the solid less permeable to acid. In other cases, the surface dissolution can produce precipitation near the surface and dissolution well below the surface. The results have implications for corrosion, including the demineralization of teeth.
