HCID 26051Sodium orthosilicate

Procedure

Namely, a proper amount of sodium hydroxide (manufactured by Nacalai Tesque Co., Ltd.) of a guaranteed reagent was dissolved into 1 liter of ion-exchanged water. 300 g of silicon dioxide (#200, manufactured by Aerosil Co. Ltd) which is commercially available was added to the dissolution and was stirred. Sodium silicate was obtained by calcining the dispersion for 5 hours at 700° C.
