gallium arsenide toxicity

Gallium arsenide contains both gallium and arsenic. Toxicol Appl Pharmacol. (NTP, 1992) Toxicity studies in experimental animal systems have shown gallium nitrate and gallium arsenide to produce toxicity to the lungs, immune system, kidneys, and hematopoietic systems. Gallium arsenide is an important semiconductor material marketed in the shape of wafers and thus is not hazardous to the end user. Comparative pulmonary toxicity of gallium arsenide, gallium(III) oxide, or arsenic(III) oxide intratracheally instilled into rats. Attacked by cold concentrated hydrochloric acid. The molten form attacks quartz. Product Name: Gallium Arsenide . Later through the reduction with carbon, arsenic is produced. In order to better appreciate the structure and the properties of gallium arsenide crystal, it is better to know more about the characteristics of the individual atoms, Arsenic and Gallium. Section 1: Identification . CAS Number: 1303-00-0 / EC Number: 215-114-8 Company: Angstrom Sciences, Inc. Exposure to GaAs particles may, however, occur during manufacture and processing. 2012 Priority List for the Development of Proposition 65 NSRLs for Carcinogens and MADLs for Chemicals Causing Reproductive Toxicity; Chemicals Listed Effective August 1, 2008 as Known to the State of California to Cause Cancer or Reproductive Toxicity: gallium arsenide, hexafluoroacetone, nitrous oxide and vinyl cyclohexene dioxide GALLIUM ARSENIDE can react with steam, acids and acid fumes. SAFETY DATA SHEET . "Gallium is actually the ideal semiconducting material, even better than silicon," says Mindiola. The International Agency for Research on Cancer (IARC) has classified gallium arsenide as a human carcinogen. The toxicological properties of gallium arsenide have not been thoroughly investigated. Reacts with bases with evolution of hydrogen. On the other hand, the crystal is stable enough that ingested pieces may be passed with negligible absorption by the body. Number: 1303-00-0 Chemical Formula: GaAs Mol. Readily attacked by the halogens. The figure below shows Bohr’s model of the atomic structures for gallium and arsenic. Gallium has been known to cause skin irritations or even dermatitis. Using current manufacturing processes, a wafer of gallium arsenide, the most popular gallium-based semiconductor material, is roughly 1,000 times more expensive than a silicon wafer. EC Inventory, C&L Inventory, PIC, REACH pre-registration, Other, Cosmetic Products Regulation, Annex II - Prohibited Substances, Protection of Pregnant and Breastfeeding Workers Directive, Annex I+II, CAD - Chemical Agents Directive, Art. GALLIUM ARSENIDE . These records shall document the procedure used when each tool was decontaminated following use with wafers containing phosphorus, arsenic, antimony, gallium, and/or … arsenic, antimony, gallium, and/or indium epitaxial or surface terminated films at CNSE. DATE OF LAST REVISION: 06/24/15. generated by newly developed gunpowder and combustion fuels, and in evaluating their threats to the health of soldiers. Gallium has been found to not be toxic, but many sources find this information to be non-conclusive. Potential hazards require evaluation. MSDS for Gallium Arsenide 1. Pubmed Abstract Wt. 1986 Mar 15;82(3):405-16. On one hand, due to its arsenic content, it is considered highly toxic and carcinogenic. "The problem is it's rare, so it's expensive." 144.64 Manufacturer: Wafer Technology Ltd Address: 34 Maryland Rd Tongwell Milton Keynes MK15 8HJ United Kingdom Tel: +44 (0)1908 210444 Fax: +44 (0)1908 210443 2.
