Coherent supplies GaAs substrates of up to 100 mm diameter, and carefully monitors 10.6 µm absorptivity to ensure that thermal runaway and fracture do not occur. Learn about the vertically integrated capabilities for material growth, fabrication, …

Arsenic derived from gallium arsenide was converted into arsenate (As III), arsenite (As V) and a major metabolite dimethyl arsinic acid, and rapidly excreted. Twenty-seven per cent of the arsenic derived from gallium arsenide were excreted in the faeces the first day after the instillation; this was probably due to lung clearance into ...

Gallium arsenide is a III–V compound direct-gap semiconductor with the Ga and As belonging to the third and fifth column of the periodic table, respectively. In the modern optoelectronics and high-speed electronics, this material is gaining prime importance.

亚砷酸盐（arsenite）As（Ⅲ）和 砷酸盐 （As（Ⅴ））被列为致癌物质。 砷是一种众所周知的环境污染物和毒物，也是毒性强大的致癌物质，它在自然界中主要以亚砷酸盐等形式存在。 在众多环境污染物中，砷位居污染 有毒元素 黑名单之首。 在许多国家，砷导致水、土壤和农作物污染。 砷及其化合物当中，三价无机砷的毒性最强，且通常以亚砷酸盐的形式存在。 亚砷酸盐可以通过呼吸道、消化道和皮肤接触进入人体，危害很多系统的正常功能，其最严重的影响是引起 肿瘤 的 …

In chemistry, an arsenite is a chemical compound containing an arsenic oxyanion where arsenic has oxidation state +3. Note that in fields that commonly deal with groundwater chemistry, arsenite is used generically to identify soluble As III anions. IUPAC have recommended that arsenite compounds are to be named as arsenate(III), for example ...

2003年12月15日 · The aim of this review is to compare the metabolism, chemistry, and biological effects to determine if either of the industrial arsenicals (arsine and gallium arsenide) act like the environmental arsenic oxides (arsenite and arsenate).

2023年5月1日 · These oxidation products (arsenite/arsenate and nickel hydroxide coating) could hinder the adsorption of xanthate onto the mineral surface, decreasing the floatability (xanthate adsorption). These results suggest that the oxidation products interfered with amyl xanthate adsorption and thereby require an excessive dosage of PAX to render the ...
