Sodium Silicate Binders for Green Sand Metalcasting Foundry
The curing of a sodium silicate solution mixed with sand is the result of complex changes that contribute to the hardening of the core or mold. Usually theCO 2 flow rate is 1 - 5 % based on silicate. Use a dry CO 2 as water is detrimental to gassing speed and overall strengths. Phenolphthalein, at a level of 0.75 % based on sand, may be used as an indicator.
How to Make Pure Sand (Silicon Dioxide) in a Lab
Jul 01, 2017 · Make Pure Sand . Mix together 5 ml sodium silicate solution and 5 ml water. In a separate container, use a glass stirrer to mix 3.5 grams sodium bisulfate into 10 mL of water. Keep stirring until the sodium bisulfate dissolves. Mix the two solutions together. The resulting gel that forms at the bottom of the liquid is orthosilicic acid.

Sodium silicate with a specific gravity of 1.40 (41.5 deg Baume) and a viscosity of 206 mPa.s (cP) at 20 °C, has been used on the majority of silicate grouting projects in the United States. This material has a weight ratio (SiO2/Na2O) of 3.22.
Pure Silicon Dioxide from Sand | Hobby Chemistry
Apr 11, 2015 · However, sand is only about 70% sand. So, only about 200g of that sand was Silicon Dioxide. So, 267g of Sodium Hydroxide react with 200g of Silicon Dioxide. However, I only used 155g of Sodium Hydroxide (about 60% of the theoretical quantity). I did so because I didn’t want to waste any Sodium Hydroxide.
Basic Facts About Colloidal Silica Densifier | Concrete Decor
Aug 19, 2013 · Silicate densifiers are compounds of silicon and a high proportion of mineral salts. (Sodium silicate molecules, for example, are 38 percent sodium by weight and only 62 percent silica. Commercial sodium silicate has even lower silica content due to contaminants.) They are also colloids, but the particle size is highly variable.
