gallium arsenide toxicity

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