If a mixture of metallic sodium and aluminium silicide is placed in water, hydrogen is evolved, with the production of sodium silicate and aluminium hydrate, in accordance with the following equation. —... 

With Aluminium.—If ordinary metallic aluminium placed in even boiling water, little or no chemical ion takes place. However, if the aluminium is first algamated with mercury it is rapidly attacked by hot ter, with the formation of aluminium hydrate and drogen, in accordance with the following equation —...

Recycling a yes score has been awarded because the CER contains a number of examples of the role played by recycling in reducing environmental impact. These include recycling aluminium oxide at Oulu, acidic sludge at Kvarntorp and aluminium hydrate at Police. The product stewardship report also includes a number of similar examples. 

Aluminium hydrate, mixed with sodium chloride and charcoal, is heated in Cl, by which a double chloride of Na and Al (2NaCl, AI,C1 ) is formed. This is then heated with Na, when Al and NaCl are produced. (The industrial process.)... 

Aluminium Hydrate—Aluminii hydros (V, aluminium salt is decompe ed by an alkali, or alkaline carbonate. It constitutes a gelatinous mass, w ch, when dried, leaves an amorphous, translucid mass and when pulverized a white, tasteless, amorphous powder. When the liquid in which it is formed contains coloring matters, these are carried down with it, and the dried deposits are used as pigments, called lak. ... 

Sodium Aluminate.—The aluminate NaaAlaO< is not known. That having the composition Na AhO is prepared by heating to redness a mixture of 1 pt. sodium carbonate and 2 pts. of a native ferruginous aluminium hydrate (beauxite). It is insoluble in HaO, and is decomposed by carbonic acid, with precipitation of aluminium hydroxid. 

Aluminates are determined gravimetrically in the usual manner 2 grammes are dissolved in water, rendered acid with HCl, excess of ammonia added, and the gelatinous precipitate of aluminium hydrate collected on a filter paper, washed, burnt, and weighed.

Thenard (1803-1804) produced cobalt blue by calcining aluminium hydrate with acetified cobalt arsenate or acetified cobalt phosphate. Church (1901) gives a recipe for this, however, to our knowledge, no arsenate nor phosphate has been found in analyses of cobalt blue in paintings. 

In 1803, Thenard showed that by calcining a mixture of aluminium hydrate with acetified cohalt phosphate or acetified cobalt arsenate one could more easily produce the pigment than with mixtures of cobalt carbonate or cobalt nitrate. Cobalt nitrate solutions would be precipitated with the acetified sodium phosphate, the purple cobalt phosphate washed with water and mixed with eight times the weight of alumina hydrate which had been precipitated with ammonia. Afterwards this mixture would be brushed onto boards for drying when it became solid and brittle it would be ground and calcined in a closed clay container for half an hour.
