99.99% Pure Gallium Metal in 100 gram quantity. Used widely in the semiconductor industry, this metal is fun to experiment with and is non-toxic unlike Mercury. A soft silvery metallic poor metal, elemental gallium is a brittle solid at low temperatures. As it liquefies slightly above room temperature, it will melt in the hand. Packed in plastic vials.

All orders with gallium ship UPS Ground Hazardous. Please select Economy  during checkout. Gallium is considered a hazardous material (specifically a class 8 corrosive) by the authorities, including the US-DOT because it can corrode aluminum.  As a result, we can only ship to the continental US and most of Canada.  The $25 Hazardous fee is included in the price.

Gallium is Atomic Element No. 31 on the periodic table of elements. One of gallium's most interesting properties is it's low melting point, just 86 degrees Fahrenheit. It remains a liquid over a wider temperature range than any other element, only coming to a boil at 4357 degrees Fahrenheit! Once a liquid, gallium holds thermal energy very well and is slow to return to a solid state after room temperature has dropped below 86 degrees. The wide liquid state range of gallium makes it a good medium for high temperature thermometers. Other uses include mirror coatings and as a component of low melting point alloys and solders.
