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