| Abstract: | The synthesis of calcium aluminum silicate hydroxide (CASH) has been carried out under mild hydrothermal and solvothermal
conditions. Different mineralizers such as HCOOH, HNO3, CH3COOH, HCl, mixed acids, NaOH and non-aqueous solvents like C2H5OH, n-butanol, glycol, methanol, etc., were employed in the synthesis of CASH. The crystals obtained were characterized by X-ray
powder diffraction and FTIR spectroscopic techniques. |
