Aluminium arsenates

Aluminium, Arsenical materials See Aluminium Arsenic trioxide, etc. [Pg.1606]

Intimate mixtures of chlorates, bromates or iodates of barium, cadmium, calcium, magnesium, potassium, sodium or zinc, with finely divided aluminium, arsenic, copper carbon, phosphorus, sulfur hydrides of alkali- and alkaline earth-metals sulfides of antimony, arsenic, copper or tin metal cyanides, thiocyanates or impure manganese dioxide may react violently or explosively, either spontaneously (especially in presence of moisture) or on initiation by heat, friction, impact, sparks or addition of sulfuric acid [1], Mixtures of sodium or potassium chlorate with sulfur or phosphorus are rated as being exceptionally dangerous on frictional initiation. [Pg.238]

Aluminium Arsenates.—The orthoarsenate, A1As04, is obtained 2 in the form of elongated lens-shaped crystals when normal sodium orthoarsenate is heated with an excess of aluminium sulphate in a sealed tube at 220° C. The crystals are hexagonal in structure, with a0 = 5-030 and c0 = 5-612 A. the form is similar to that of quartz.3... [Pg.190]

A mixture of aluminium arsenate, lime and sand has been recommended as a hydraulic cement on dehydration insoluble calcium arsenate is formed, which improves the resistance to disintegration.4... [Pg.190]

Aluminium arsenate occurs in numerous minerals. Liskeardite, (Al, Fe)As04-8H20, is found in Cornwall as a pale blue incrustation on... [Pg.190]

YSART G E, MILLER P F, CREWS H, ROBB P, BAXTER M, DE L ARGY C, lofthouse s, sargent c and Harrison N, 1997 UK total diet study -dietary exposures to aluminium, arsenic, cadmium, chromium, copper, lead, mercury, nickel, selenium, tin and zinc, Food Additives and Contaminants, 2000 17 775-86. [Pg.166]

A number of investigations of metal-containing biomolecules are described in this chapter. The elements include aluminium, arsenic, cadmium, copper, gold, lead, platinum and zinc. [Pg.403]

Our main discussion of the MOCVD preparation of III-V semiconductors is in Section III.A. Single-source precursors for III-V semiconductors have shown advantages and [Bu2 s.AlEt2]2 has been proposed by Cowley and coworkers as such a source. Other possibilities are available such as Et2A1 AsCHMe CHMe CHMe dHMe . Aluminium containing III-V semiconductors are often ternary phases. Cowley and coworkers have synthesized a potential ternary precursor containing an aluminium/arsenic moiety. [Pg.529]

Metals and their compounds are a further group of substances with toxic effects on the lung. This is a relatively limited group including the following elements aluminium, arsenic, beryllium, cadmium, chromium, cobalt, copper and nickel. Effects on the lung induced by their compounds are mostly caused solely by the metal part of these substances. Only in a limited number of cases are the effects on the lungs attributed to the entire metal compound. [Pg.797]

The chapters in Part II are also written by scientists with a broad practical experience. They contain detailed information for the analysis in biological specimens of the thirteen trace elements that are most important for toxicological, epidemiological and environmental studies Aluminium, arsenic, cadmium, chromium, copper, lead, manganese, mercury, nickel, selenium, thallium, vanadium, and zinc. [Pg.2]

This reaction (Eq. 2.245) has been employed to prepare binary and mixed aUcoxide-iV,iV-diethylaminooxide derivatives of titanium,niobium, tantalum, boron, aluminium, " arsenic, and antimony. ... [Pg.126]

In addition to minerals which are known to be dietary essentials, there a number which may be consumed in relatively large amounts but which have, as far as is known, no function in the body. Indeed, excessive accumulation of these minerals may be dangerous, and a number of them are well known as poisons. Such elements include aluminium, arsenic, antimony, boron, cadmium, caesium, germanium, lead, mercury, silver and strontium. [Pg.415]
