Effect of calcium source on structure and properties of sol–gel derived bioactive glasses [PDF]

open access: yes, 2012
The aim was to determine the most effective calcium precursor for synthesis of sol–gel hybrids and for improving homogeneity of sol–gel bioactive glasses. Sol–gel derived bioactive calcium silicate glasses are one of the most promising materials for bone

Effects of calcium and magnesium silicate on the absorption of silicon and nutrients in wheat

open access: yesSemina: Ciências Agrárias, 2019
Wheat is a plant that accumulates silicon (Si). The application of silicon to the soil may influence the absorption of nutrients by the plant and, therefore, its nutritional balance.

Bond strength of a calcium silicate-based sealer tested in bulk or with different main core materials

open access: yesBrazilian Oral Research, 2014
The aim of this study was to evaluate the influence of a calcium silicate-based sealer (iRoot SP), with or without a core material, on bond strength to radicular dentin, in comparison with various contemporary root filling systems. Root canals of freshly

Calcium Silicates as Lime Substitute

open access: yesWater Science and Technology, 1993
An experimental study has been carried out of the removal of iron from solutions of ferric chloride by lime, β-dicalcium silicate (C2S) and α-monocalcium silicate (CS) and of the treatment of the resulting sludge. C2S promoted the flocculation of iron precipitates to achieve higher settling, thickening and dewatering rates.
