A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text.
Bioactivity of Calcium Aluminate Endodontic Cement
In water, calcium aluminate cement's main phases, calcium aluminate (CaO · Al 2 O 3) and calcium dialuminate (CaO · 2Al 2 O 3), are decomposed, releasing Ca 2+, Al(OH) 4 −, and OH − ions . When the solubility products for hydrate phases are reached, calcium aluminate hydrate and aluminum hydroxide precipitate.
