Sodium silicate can be used to fill gaps in the head gasket of an engine. This is especially useful for aluminum alloy cylinder heads, which are sensitive to thermally induced surface deflection. Sodium silicate is added to the cooling system through the radiator and allowed to circulate. When the sodium silicate reaches its "conversion ...
Sodium metasilicate is the chemical substance with formula Na. 2SiO. 3, which is the main component of commercial sodium silicate solutions. It is an ionic compound consisting of sodium cations Na+. and the polymeric metasilicate anions [– SiO2−. 3 –] n. It is a colorless crystalline hygroscopic and deliquescent solid, soluble in water ...
The specific heat of the human body calculated from the measured values of individual tissues is 2.98 kJ · kg−1 · °C−1. This is 17% lower than the earlier wider used one based on non measured values of 3.47 kJ · kg−1· °C−1. The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution ...
Faujasite (FAU-type zeolite) is a mineral group in the zeolite family of silicate minerals.The group consists of faujasite-Na, faujasite-Mg and faujasite-Ca. They all share the same basic formula (Na 2,Ca,Mg) 3.5 [Al 7 Si 17 O 48]·32(H 2 O) by varying the amounts of sodium, magnesium and calcium. [1]
A silicate is any member of a family of polyatomic anions consisting of silicon and oxygen, usually with the general formula [SiO(4-2x)−. 4−x] n, where 0 ≤ x < 2. The family includes orthosilicate SiO4− 4 (x = 0), metasilicate SiO2− 3 (x = 1), and pyrosilicate Si2O6− 7 (x = 0.5, n = 2). The name is also used for any salt of such ...
Water glass ( sodium silicate [Na 2 SiO 3 or (Na 2 O)(SiO 2)] ) is a high strength binder used with silica molding sand both for cores and molds. [ 22 ] : 69–70 To cure a mixture of finely ground sand (e.g. by using a sand muller) and 3 to 4% of sodium silicate the binder, carbon dioxide (CO 2 ) gas is used.
A silicate mineral is generally an inorganic compound consisting of subunits with the formula [SiO 2+n] 2n−. Although depicted as such, the description of silicates as anions is a simplification. Balancing the charges of the silicate anions are metal cations, M x+. Typical cations are Mg 2+, Fe 2+, and Na +.
Vermiculite is a 2:1 clay, meaning it has two tetrahedral sheets for every one octahedral sheet. It is a limited-expansion clay with a medium shrink–swell capacity. Vermiculite has a high cation-exchange capacity (CEC) at 100–150 meq /100 g. Vermiculite clays are weathered micas in which the potassium ions between the molecular sheets are ...
