Sodium silicate solutions can also be used as a spin-on adhesive layer to bond glass to glass [21] or a silicon dioxide–covered silicon wafer to one another. [22] Sodium silicate glass-to-glass bonding has the advantage that it is a low-temperature bonding technique, as opposed to fusion bonding. [21]
Sodium metasilicate is the chemical substance with formula Na 2 SiO 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 [– SiO 2− 3 –] n.
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
An aqueous solution of sodium silicate is acidified to produce a gelatinous precipitate that is washed, then dehydrated to produce colorless silica gel. [6] When a visible indication of the moisture content of the silica gel is required, ammonium tetrachlorocobaltate(II) (NH 4) 2 [CoCl 4] or cobalt(II) chloride CoCl 2 is added. [6]
Sulfuric acid and sodium silicate solutions are added simultaneously with agitation to water. Precipitation is carried out under acidic or basic conditions. The choice of agitation , duration of precipitation, the addition rate of reactants, their temperature and concentration and pH can vary the properties of the resulting silica.
Sheet silicates. In this group, known as phyllosilicates, tetrahedra all share three oxygen atoms each and in turn link to form two-dimensional sheets. This structure does lead to minerals in this group having one strong cleavage plane. Micas fall into this group. Both muscovite and biotite have very weak layers that can be peeled off in sheets.
Sodium silicide (NaSi, Na 4 Si 4) is a binary inorganic compound consisting of sodium and silicon. It is a solid black or grey crystalline material. [1] Sodium silicide reacts readily with water yielding gaseous hydrogen and aqueous sodium silicate in an exothermic reaction (~175 kJ·mol −1): [2] 2 NaSi + 5 H 2 O → 5 H 2 + Na 2 Si 2 O 5
Calcium silicate can refer to several silicates of calcium including: 2CaO·SiO 2, larnite (Ca 2 SiO 4) 3CaO·SiO 2, alite or (Ca 3 SiO 5) 3CaO·2SiO 2, (Ca 3 Si 2 O 7) CaO·SiO 2, wollastonite (CaSiO 3). This article focuses on Ca 2 SiO 4, also known as calcium orthosilicate. It is also referred to by the shortened trade name Cal-Sil or Calsil.
