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]

3. Paper chemicals - Wikipedia

   en.wikipedia.org/wiki/Paper_chemicals

   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. Sodium aluminosilicate - Wikipedia

   en.wikipedia.org/wiki/Sodium_aluminosilicate

   Sodium aluminosilicate refers to compounds which contain sodium, aluminium, silicon and oxygen, and which may also contain water. These include synthetic amorphous sodium aluminosilicate, a few naturally occurring minerals and synthetic zeolites. Synthetic amorphous sodium aluminosilicate is widely used as a food additive, E 554.

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. Beta-alumina solid electrolyte - Wikipedia

   en.wikipedia.org/wiki/Beta-alumina_solid_electrolyte

   The temperature difference between the two regions gives rise to a certain sodium activity differential, the sodium expands almost isothermally. Since the beta alumina electrolyte does not conduct electrons favourably the expansion causes sodium ions across the membrane and the electrons through an external circuit.
