(NTP, 1992) Wt. Exposure to GaAs particles may, however, occur during manufacture and processing. 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. Later through the reduction with carbon, arsenic is produced. The figure below shows Bohr’s model of the atomic structures for gallium and arsenic. "Gallium is actually the ideal semiconducting material, even better than silicon," says Mindiola. GALLIUM ARSENIDE . PRODUCT AND COMPANY IDENTIFICATION Product Name: Gallium Arsenide C.A.S. 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 Toxicol Appl Pharmacol. The molten form attacks quartz. arsenic, antimony, gallium, and/or indium epitaxial or surface terminated films at CNSE. 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. Gallium arsenide contains both gallium and arsenic. Attacked by cold concentrated hydrochloric acid. Gallium has been known to cause skin irritations or even dermatitis. generated by newly developed gunpowder and combustion fuels, and in evaluating their threats to the health of soldiers. "The problem is it's rare, so it's expensive." CAS Number: 1303-00-0 / EC Number: 215-114-8 Company: Angstrom Sciences, Inc. Pubmed Abstract Comparative pulmonary toxicity of gallium arsenide, gallium(III) oxide, or arsenic(III) oxide intratracheally instilled into rats. Section 1: Identification . Reacts with bases with evolution of hydrogen. 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. SAFETY DATA SHEET . Gallium has been found to not be toxic, but many sources find this information to be non-conclusive. The U. S. Army requires an instrument for monitoring gaseous by-products, including HCL, NO2, CO2, CO, etc. Gallium arsenide is an important semiconductor material marketed in the shape of wafers and thus is not hazardous to the end user. 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. The toxicological properties of gallium arsenide have not been thoroughly investigated. Product Name: Gallium Arsenide . DATE OF LAST REVISION: 06/24/15. On one hand, due to its arsenic content, it is considered highly toxic and carcinogenic. GALLIUM ARSENIDE can react with steam, acids and acid fumes. The International Agency for Research on Cancer (IARC) has classified gallium arsenide as a human carcinogen. Number: 1303-00-0 Chemical Formula: GaAs Mol. R – This substance was identified as toxic to reproduction ... Gallium arsenide. On the other hand, the crystal is stable enough that ingested pieces may be passed with negligible absorption by the body. 1986 Mar 15;82(3):405-16. Potential hazards require evaluation. 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. These records shall document the procedure used when each tool was decontaminated following use with wafers containing phosphorus, arsenic, antimony, gallium, and/or … Readily attacked by the halogens.
