CAS MSDS (GALLIUM ARSENIDE) Melting Point Boiling Point Density CAS Chemical Properties

Do not work with any dust from any semiconductor period. Such good mechanical characteristics also make it a suitable material for the rapidly developing field of nanoelectronics.

I’ve looked at various data over the past couple of days on this stuff and they all seem to say the crystal is safe gaass GaAs, but can liberate As and Ga compounds in contact with acids etc. By using this site, you agree to the Terms of Use and Privacy Policy. Do not let product enter drains. If not breathing, give artificial respiration.

Monitor for pulmonary edema and treat if necessary Department of Transportation, website: Relative vapour density no data available Particle characteristics no data available Accidental release measures 6. Msdz index n D. Discharge into the environment must be avoided. This evaluation applies to the group of chemicals as a whole and not necessarily to all individual chemicals within the group. Contaminated packaging Ggaas can be triply rinsed or equivalent and offered for recycling or reconditioning.


When heated to decomposition, this compound emits very toxic fumes of arsenic. Stability and reactivity Silicon dioxide can be incorporated onto silicon circuits easily, and such layers are adherent to the underlying silicon. If you do not see the specification you require, please ask for details Download PDF datasheet. Critical Reviews in Toxicology. Provide appropriate exhaust ventilation at places where dust is formed.

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. In case of eye contact Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.

If inhaled If breathed in, move person into fresh air. It does not represent any guarantee of the properties of the product.


Packaging Polished Wafers Fluoroware type tray, individually mssds in two outer bags in inert atmosphere. The GaAs solar cells, manufactured by Kvant, were chosen because of their higher performance in high temperature environments.


This kind of solar cell powers the Mars Exploration Rovers Spirit and Opportunitywhich are gaax Mars ‘ surface. This low carrier concentration is similar to an intrinsic perfectly undoped crystal, but much easier to achieve in practice. Watch for signs of respiratory insufficiency and assist ventilations if needed.

First, silicon is abundant and cheap to process in the form of silicate minerals. Avoid breathing vapours, mist or gas.

Readily attacked by the halogens. 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 gzas, anuria, liver damage, jaundice, hematuria, proteinuria and leukopenia.

Semiconductor Devices Physics and Technology. Journal of Crystal Growth. Use personal protective equipment. Another advantage of GaAs is that it has a direct band gapwhich means that it can be used to absorb and emit light efficiently.
