Alkaline Silicate Solutions An Overview of Their
· The most reactive alkaline solutions have alkali cation concentrations ranging from 4.5 to 9.5 mol/L. For the sand agglomeration application it was shown that the used solutions are highly polymerized. In addition the drying temperature and the method employed influence the silicate distribution in the final material.

sodium silicateATDMDrilling
Sodium silicate is a soluble chemical in water in various physical shapes. Formed by dissolving silica or silicate minerals in NaOH solutions. The silicate anion SiO4-4 is found in solutions of sodium-silicate. Silicate anions form polysilicates or colloidal silica gel. A silicate mud is a type of shale-inhibitive water base drilling fluid

The inhibition efficiency of PAMALAM at 20 ppm dosage appears to be lower and indistinguishable from the control (˘200 ppm soluble silicate). Silicate polymerization continues after 48 h. In control solutions soluble silicate levels drop to 170 ppm (loss of ˘30

Difference Between Colloidal Silica and Reactive Silica
· Reactive silica is any monomeric silica including the ionized forms and potentially any dissolved dimer of silicon. In other words reactive silica is the non-polymeric form of silica. There are different methods we can use to remove reactive silica from a water supply.

· reacting with metal pipes. Therefore a fresh source of "reactive" SiO2is needed (as from soluble silicate solutions). LENGTH OF CARRY When silicate treatment is first started the system near the point of applica-tion is coated immediately then the film continues to form at greater dis-tances.
The Root of Silica Scale Formation and Its Remedy
· Silica in water can be as reactive silica colloidal silica and particulate silica. Silicate compounds exist in the form of amorphous which is soluble in alkali solutions and crystalline form is nonstable. When pH exceed neutral silicic acid can be dissociated and form silicate anions (SiO 3 2-). which can react positive ions like Ca Mg Fe Mn
High Temperature Plug Formation With Silicates
· A reactive grout material would be injected through the drill string to the hole bottom and allowed to flow into the loss zone and the immediate polyvalent metal ions to produce metal silicate precipitates that are less soluble across a broader pH range than the metal hydroxides produced by non-silicate processes.
