Mar 18 2017 · IGBC samples also showed better strength (compared to IGC but still their strength was low when we compare with IG due to higher amount of sodium silicate used in processing of IGBC.) as a result of C O b.2 produced from sodium bicarbonate which is helpful in mobilization of aluminum ions and fast hardening of silica network. Nov 12 2015 · Who said in a later post I wanted to experiment with it as a refractory glue. So I now realise that he probably wants/needs the sodium silicate as strong as he can get it.

I had a bunch of silica gel so I decided to try making up some sodium silicate. 55 grams of silica gel beads were placed in water in a beaker and 37 grams o The big question in my mind here is how deeply the forge s high temps will soak into the surface of the forge and whether that castable refractory would be sufficient to contain the mix if it melts. Sodium silicate and Perlite both melt at less than 2000F so even to use this mixture as secondary insulation is a

A person could MIGHT use it as a backer if there were enough good refractory between it and the flame. Perlite starts degrading rapidly around 2 000f say the bright orange part of the camp fire when you blow on it.

Since sodium silicate is also used in the manufacture of hi-temp mortar I ve often wondered whether it would be worth adding to a regular clay-sand mix. So I made a clay waterglass mix that was approximately 4 parts wet clay to 1 part waterglass. The clay had roughly the consistency of thick peanut butter or bean paste. Sodium silicate is a white solid that is soluble in water producing an alkaline solution. There are many kinds of this compound including sodium orthosilicate Na 4 SiO 4 sodium metasilicate Na 2 SiO 3 sodium polysilicate (Na 2 SiO 3) n sodium pyrosilicate Na 6 Si 2 O 7 and others. All are glassy colourless and dissolve in water.
