2. Sodium aluminate - Wikipedia

   en.wikipedia.org/wiki/Sodium_aluminate

   In construction technology, sodium aluminate is employed to accelerate the solidification of concrete, mainly when working during frost. Sodium aluminate is also used in the paper industry, for fire brick production, alumina production and so forth. Sodium aluminate solutions are intermediates in the production of zeolites. [8] [9]

   Chemical pulping involves dissolving lignin in order to extract the cellulose from the wood fiber. The different processes of chemical pulping include the Kraft process, which uses caustic soda and sodium sulfide and is the most common; alternatively, the use of sulfurous acid is known as the sulfite process, the neutral sulfite semichemical is treated as a third process separate from sulfite ...

4. Aluminate - Wikipedia

   en.wikipedia.org/wiki/Aluminate

   Sodium aluminate, NaAlO 2, is used industrially in dyeing to form a mordant and the hydrated forms are used in water purification, sizing of paper and in the manufacture of zeolites, ceramics and catalysts in the petrochemical industry. In the isomerization process of alkenes and amines [12] Calcium aluminates are important ingredients of ...

5. Deville process - Wikipedia

   en.wikipedia.org/wiki/Deville_process

   The first stage is the calcination of the bauxite at 1200 °C with sodium carbonate and coke. The alumina is converted in sodium aluminate. Iron oxide remains unchanged and silica forms a polysilicate. In the second stage sodium hydroxide solution is added, which dissolves the sodium aluminate, leaving the impurities as a solid residue. The ...

6. Aluminium oxide - Wikipedia

   en.wikipedia.org/wiki/Aluminium_oxide

   Aluminium oxide is an amphoteric substance, meaning it can react with both acids and bases, such as hydrofluoric acid and sodium hydroxide, acting as an acid with a base and a base with an acid, neutralising the other and producing a salt. Al 2 O 3 + 6 HF → 2 AlF 3 + 3 H 2 O Al 2 O 3 + 2 NaOH + 3 H 2 O → 2 NaAl(OH) 4 (sodium aluminate)

7. Sodium hydroxide - Wikipedia

   en.wikipedia.org/wiki/Sodium_hydroxide

   The reaction thus produces hydrogen gas and sodium aluminate. In this reaction, sodium hydroxide acts as an agent to make the solution alkaline, which aluminium can dissolve in. 2 Al + 2 NaOH + 2 H 2 O → 2 NaAlO 2 + 3 H 2. Sodium aluminate is an inorganic chemical that is used as an effective source of aluminium hydroxide for many industrial ...
