Sodium silicate solutions can also be used as a spin-on adhesive layer to bond glass to glass [21] or silicon oxide covered silicon wafers 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]
Forge welding (FOW), also called fire welding, is a solid-state welding process [1] that joins two pieces of metal by heating them to a high temperature and then hammering them together. [2] It may also consist of heating and forcing the metals together with presses or other means, creating enough pressure to cause plastic deformation at the ...
Lithium (from Ancient Greek λίθος (líthos) 'stone'; symbol Li and atomic number 3) is a soft, silvery-white alkali metal. Under standard conditions, it is the least dense metal and the least dense solid element. Like all alkali metals, lithium is highly reactive and flammable, and must be stored in vacuum, inert atmosphere, or inert ...
Illustrative is the production of sodium tetrasulfide: 4 Na + S 8 → 2 Na 2 S 4. Some of these dianions dissociate to give radical anions, such as S 3 − gives the blue color of the rock lapis lazuli. Two parallel sulfur chains grown inside a single-wall carbon nanotube (CNT, a). Zig-zag (b) and straight (c) S chains inside double-wall CNTs [3]
Sodium hypochlorite is an alkaline inorganic chemical compound with the formula Na O Cl (also written as NaClO). It is commonly known in a dilute aqueous solution as bleach or chlorine bleach. [4] It is the sodium salt of hypochlorous acid, consisting of sodium cations (Na +) and hypochlorite anions (− OCl, also written as OCl − and ClO −
Borax (also referred to as sodium borate, tincal ( / ˈtɪŋkəl /) and tincar ( / ˈtɪŋkər / )) is a salt ( ionic compound), a hydrated or anhydrous borate of sodium, with the chemical formula Na 2 H 20 B 4 O 17 (also written as Na 2 B 4 O 7·10H2O[ 1][ a] ). It is a colorless crystalline solid that dissolves in water to make a basic solution .
Forging a nail. Valašské muzeum v přírodě, Czech Republic. Forging is one of the oldest known metalworking processes. [1] Traditionally, forging was performed by a smith using hammer and anvil, though introducing water power to the production and working of iron in the 12th century allowed the use of large trip hammers or power hammers that increased the amount and size of iron that could ...
Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...
