Pottery. Sodium silicate is used as a deflocculant in casting slips helping reduce viscosity and the need for large amounts of water to liquidize the clay body. It is also used to create a crackle effect in pottery, usually wheel-thrown. A vase or bottle is thrown on the wheel, fairly narrow and with thick walls.
Soda–lime glass, also called soda–lime–silica glass, is the most prevalent type of glass, used for windowpanes and glass containers (bottles and jars) for beverages, food, and some commodity items. Some glass bakeware is made of soda-lime glass, as opposed to the more common borosilicate glass. [1] Soda–lime glass accounts for about 90% ...
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal ...
Dealkalization is a process of surface modification applicable to glasses containing alkali ions, wherein a thin surface layer is created that has a lower concentration of alkali ions than is present in the underlying, bulk glass. This change in surface composition commonly alters the observed properties of the surface, most notably enhancing ...
The subunits of colloidal silica particles are typically in the range of 1 to 5 nm. Whether or not these subunits are joined depends on the conditions of polymerization. Initial acidification of a water-glass (sodium silicate) solution yields Si(OH) 4. If the pH is reduced below 7 or if salt is added, then the units tend to fuse together in chains.
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 ...
Bottled water. Bottled water is drinking water (e.g., well water, distilled water, reverse osmosis water, mineral water, or spring water) packaged in plastic or glass water bottles. Bottled water may be carbonated or not, with packaging sizes ranging from small single serving bottles to large carboys for water coolers.
Silica fibers are fibers made of sodium silicate (water glass). They are used in heat protection (including asbestos substitution) and in packings and compensators. They can be made such that they are substantially free from non- alkali metal compounds. Sodium silicate fibres may be used for subsequent production of silica fibres, which is ...
