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