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