Effect of Lithium Ions on the Properties of Calcium Sulfate Cement Materials

— We have studied calcium sulfate (CS) based cement materials containing up to 5 mol % lithium cations. The presence of lithium ions has been shown to increase the solubility of the CS cements in Dulbecco’s solution, which is accompanied by an increase in the pH of extracts from 6.0 to 8.7. Lithium...

Description
Summary:— We have studied calcium sulfate (CS) based cement materials containing up to 5 mol % lithium cations. The presence of lithium ions has been shown to increase the solubility of the CS cements in Dulbecco’s solution, which is accompanied by an increase in the pH of extracts from 6.0 to 8.7. Lithium cations were detected in Dulbecco’s phosphate buffered saline during the first 24 h of the experiment, and a calcium phosphate layer was formed on the surface of the lithium-containing CS cements during the seventh day. The presence of lithium ions has been shown to cause a twofold decrease in the temperature of the transition from calcium sulfate dihydrate to the hemihydrate.
