Sodium silicate solution is used to inexpensively, quickly, and permanently disable automobile engines. Running an engine with about 2 liters of a sodium silicate solution instead of motor oil causes the solution to precipitate, catastrophically damaging the engine’s bearings and pistons within a few minutes.
Salt will not dissolve in gasoline but it will in any water in the tank. Then it will slowly corrode the bottom of the tank. Its unlikely to make it into the engine but you never know. The salt crystals may be sucked into the fuel pump and clog its filter so then the engine might not run.
What does sodium silicate do in coolant?
Silicate gel buildup greatly reduces heat transfer from the engine castings to the coolant. When the gel coats the temperature sender, engine overheating can take place without notice. Silicate gel also carriers abrasive particles to the water pump, where it wears away pump seals causing leakage and failure.
How much sodium silicate should I use in the radiator?
Typically, in an automotive combustion engine having a 16 quart coolant capacity, the weight amount of sodium silicate being introduced into the cooling system is between from about 3 to about 8 ounces (from about 85 to about 225 grams).
What does sodium silicate do to an engine? – Related Questions
How long does sodium silicate take to cure?
Drying Times:
Sodium Silicate is a water based liquid and drying me is a funcon of how quickly the water can be evaporated. A thin layer exposed to air will dry in about 30 minutes, however most applicaons will require at least 24 hours to dry due to limited air flow.
What happens if you touch sodium silicate?
Health Effects
The pH typically ranges from 11.2 to 12.7. This property makes sodium silicate solutions irritating to the skin, mucous membranes and eyes. Contact with the eyes can cause severe irritation, pain, and corneal burns possibly leading to blindness. Direct contact with the skin may cause irritation.

Is sodium silicate a hardener?
Sodium silicate solution is a clear water-soluble, premium sodium silicate concrete hardener that assists in the curing*, hardening and dust proofing of concrete.
How strong is sodium silicate?
Sodium silicate–ester grouts can give strengths from a few hundred kPa to a few MPa with set times from about 10 minutes to 2 hours. Initial grout solution viscosities may be of order 5 to 40. Strength and viscosity will be very sensitive to the concentration of silicate in the grout.
Is sodium silicate a flocculant?
Sodium silicate is used as a dispersant in the selective flocculation of iron ores with starch as the polymeric floccullant. The mechanism of its dispersive effect on quartz has been reported to be related to its ability to remove coagulants, such as calcium and magnesium ions, from the process water.
What is the common name of sodium silicate?
Sodium silicate is also the technical and common name for a mixture of such compounds, chiefly the metasilicate, also called waterglass, water glass, or liquid glass.
What is the pH of sodium silicate?
Sodium silicate [(SiO2)n. Na2O, n<4] that was used as a precursor for synthesis of precipitated silica has the initial pH in the range of 11-1312.
Silica dust particles become trapped in lung tissue causing inflammation and scarring. The particles also reduce the lungs’ ability to take in oxygen. This condition is called silicosis. Silicosis results in permanent lung damage and is a progressive, debilitating, and sometimes fatal disease.
Is sodium silicate a salt?
Sodium silicate is an inorganic sodium salt having silicate as the counterion. It contains a silicate ion.
What temperature can sodium silicate withstand?
Characteristics of Adhesive Materials
This material will withstand temperatures of up to 1100 °C. The main applications of sodium silicate adhesives are in bonding paper and making corrugated boxboard, boxes, and cartons.
