Alternatively, the packaging can be punctured to make gass unusable for other purposes and then be disposed of in a sanitary landfill. For US version, EU version 23 languages and more, please refer to xixisys.

Autumn Safety Kid Safety Looking for safety pic.


Department of Transportation, website: GaAs – Gallium Arsenide Wafer Technology offers single crystal gallium arsenide grown at low pressure from high purity polycrystalline gallium arsenide in a vertical temperature gradient VGF-Vertical Gradient Freeeze. Use personal protective equipment. The information in this document is based on the present state of our knowledge and is applicable to the product with regard to appropriate safety precautions.

Mscs swallowed Never give anything by mouth to an unconscious person. Relative vapour density no data available Particle characteristics no data available Cover skin burns with dry sterile dressings after decontamination From Extraterrestrial to Terrestrial Applications”.

Provide appropriate exhaust ventilation at places where dust is formed. This kind of solar cell powers the Mars Exploration Rovers Spirit and Opportunitywhich are exploring Mars ‘ surface.

I was never given proper gear to separate myself from the dust which can stick to your hands underneath your fingernails. These superior properties are compelling reasons to use GaAs circuitry in mobile phonessatellite communications, microwave point-to-point links and higher frequency radar systems.


About this time I got really sick somehow. I’m gonna “no bid” on this one and offer him Germanium instead. In the early s, the efficiency of the best GaAs solar cells surpassed that of conventional, crystalline silicon -based solar cells.

Safety glasses with side-shields conforming to EN Because GaAs and AlAs have almost the same lattice constantthe layers have very little induced strainwhich allows them to be grown almost arbitrarily thick. Tags for this Thread nottoxic. Establish a patent airway.

If not breathing, give artificial respiration. Follow us on All times are GMT Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. Journal of Crystal Growth. Do not let product enter drains. Watch for signs of respiratory insufficiency and assist ventilations if needed. NIOSH usually recommends that occupational exposures to carcinogens be limited to the lowest feasible concentration.

Vaas machined this stuff? I have searched all day for info on this stuff and although it says there’s nothing on GaAs being toxic, I have found comprehensive and sometimes contradictory information on Arsenic and Gallium compounds being bad.

GaAs has been used to produce near-infrared laser diodes since Do not discharge to sewer systems.

Gallium arsenide

This allows extremely high performance meds high electron mobility HEMT transistors and other quantum well devices. Packaging Polished Wafers Fluoroware type tray, individually sealed in two outer bags in inert atmosphere. Toxicological information Acute toxicity Oral: From Wikipedia, the free encyclopedia. Uses advised against no data available 1. Discharge into the environment must be avoided.


GaAs diodes can be used for the detection of X-rays. Accidental release measures 6. I work with GaAs wafers, but I’m not a safety guy, so I’m sure there’s a lot more you need to know. Because of its wide bandgap, pure GaAs is highly resistive.

Some electronic properties of gallium arsenide are superior to those of silicon.

In msrs s, GaAs solar cells took over from silicon as the cell type most commonly used for photovoltaic arrays for satellite applications. Critical Reviews in Toxicology.

National Institutes of Health. Symptoms of exposure to this compound may include diarrhea, hypotension, weakness, cardiac failure, convulsions, coma, nervousness, headache, dizziness hypothermia, abdominal cramps, irritability, paralysis, cardiac arrhythmia, respiratory edema, dyspnea, cyanosis, coughing, peripheral neuropathy, optic neuritis, anesthesia, paresthesia, alopecia, dermatitis, cirrhosis of the liver, salivation, aplastic anemia, kidney damage, anuria, liver damage, jaundice, hematuria, proteinuria and leukopenia.

Skin protection Wear impervious gaaz. For manufacturing solar cells, silicon has relatively low absorptivity for sunlight, meaning about micrometers of Si is needed to absorb most sunlight. Msdds as supplier shall not be held liable for any damage resulting from handling or from contact with the above product.

Gallium arsenide single crystals can be prepared by three industrial processes: Semiconductor laser theory Laser diode rate equations. Gallium arsenide GaAs is a compound of the elements gallium and arsenic.
