Sodium aluminate is an inorganic chemical that is used as an effective source of aluminium hydroxide for many industrial and technical applications. Pure sodium aluminate is a white crystalline solid having a formula variously given as NaAlO 2, NaAl(OH) 4 (), [3] Na 2 O·Al 2 O 3, or Na 2 Al 2 O 4.
6 O 18− 18 anion, found in tricalcium aluminate, Ca 3 Al 2 O 6, which can be considered to consist of 6 corner sharing {AlO 4} tetrahedra. [5] A number of infinite chain anions in the compounds Na 7 Al 3 O 8 which contains rings linked to form chains, Na 7 Al 13 O 10 and Na 17 Al 5 O 16 which contain discrete chain anions. [6]
Sodium oxide is a chemical compound with the formula Na 2 O.It is used in ceramics and glasses.It is a white solid but the compound is rarely encountered. Instead "sodium oxide" is used to describe components of various materials such as glasses and fertilizers which contain oxides that include sodium and other elements.
For example, 15-crown-5 has a high affinity for sodium because the cavity size of 15-crown-5 is 1.7–2.2 Å, which is enough to fit the sodium ion (1.9 Å). [ 19 ] [ 20 ] Cryptands, like crown ethers and other ionophores , also have a high affinity for the sodium ion; derivatives of the alkalide Na − are obtainable [ 21 ] by the addition of ...
[3] [4] The compound β-alumina was already discovered in 1916 and the structure was quite well known by the end of the 1930s. The term "beta-alumina" is a misnomer, [5] since it is not an aluminium oxide (Al 2 O 3), but a sodium polyaluminate. Before the 1970s, β-alumina was mainly used in the construction of industrial furnaces.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Aluminium oxide (or aluminium(III) oxide) is a chemical compound of aluminium and oxygen with the chemical formula Al 2 O 3.It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium oxide.
Sodium superoxide is the inorganic compound with the formula Na O 2. [1] This yellow-orange solid is a salt of the superoxide anion. It is an intermediate in the oxidation of sodium by oxygen.
