Gallium Metal 4N (99.99%)

Q: What is Gallium Metal?

Gallium metal is the elemental form of gallium (Ga), a soft, silvery-white metal that melts at 29.76 °C. In addition, buyers use it in low-melting alloys, research and as a starting material for gallium compounds.

Q: What is the chemical formula of Gallium Metal?

Gallium metal is an element, so its formula is simply its chemical symbol, Ga. Also, its atomic number is 31 and its atomic weight is 69.723 g/mol.

Q: What is the CAS number of Gallium Metal?

The CAS number of gallium metal is 7440-55-3. Therefore, quote this number when you source the material.

Q: What does 4N purity mean?

4N means "four nines," or 99.99% purity. In other words, total impurities make up no more than 0.01% of the material, which equals 100 ppm.

Q: What is Gallium Metal used for?

Buyers use gallium metal for low-melting alloys, chemical synthesis of gallium compounds, advanced materials development and laboratory research. It is also the starting material for compound semiconductors such as GaAs and GaN, although wafer-grade production usually requires higher-purity gallium than 4N.

Q: What does the COA specify?

The COA specifies 99.99% minimum gallium purity. In addition, aluminium, calcium, nickel, zinc and indium are each below 1.0 ppm wt, whereas iron, copper, tin, lead and all other impurities are each below 5.0 ppm wt.

Q: What is the melting point of gallium?

Gallium melts at 29.76 °C (85.57 °F). For this reason, solid gallium can turn into liquid gallium with gentle warming, or even in the palm of your hand.

Q: How much does gallium metal cost?

The gallium metal price depends on purity, quantity, supplied form and current market conditions. Therefore, contact Neugen Labs with your specification and quantity for an up-to-date quote.

Q: Where can I buy gallium metal in the USA?

You can buy Gallium Metal 4N (99.99%) from Neugen Labs, a specialty chemical supplier based in Tampa, Florida. Simply request a quote on the product page or contact us with your requirements.

Q: What packaging options are available?

Please contact Neugen Labs for current packaging options and the supplied form of the material. Then we will confirm the details with your quotation.

What Is Gallium Metal?

Gallium metal (element Ga, atomic number 31) is a soft, silvery-white metal with an unusually low melting point. In fact, the gallium melting point is just 29.76 °C. As a result, solid gallium turns into liquid gallium slightly above room temperature and then stays liquid over a very wide temperature range. For this reason, gallium is the starting point for many materials in electronics, alloys and research.

However, elemental gallium is not the same material as gallium oxide (Ga₂O₃), gallium arsenide (GaAs) or gallium nitride (GaN). Instead, those are separate compounds with their own properties and specifications. Manufacturers make them from gallium metal, but gallium metal cannot replace them.

Our pure gallium is a 4N grade with 99.99% minimum gallium content. In addition, the COA limits each impurity at the ppm level. Therefore, it suits buyers who need documented, high purity gallium metal rather than a hobby-grade sample.

Uses & Applications

Industry uses gallium both as a metal and as a starting material for gallium compounds. The applications below show where gallium and gallium-containing materials typically appear. However, you should always check the COA against your own process requirements before you choose this 4N grade.

Specialized Alloys

Gallium forms low-melting alloys with indium and tin, such as Galinstan-type and eutectic gallium-indium alloys, that stay liquid at room temperature:

Galinstan-type alloysGallium-indium eutecticThermal interfacesFusible alloys

Semiconductor Materials

Gallium is a constituent of compound semiconductors. However, these are separate materials, and wafer-grade production usually calls for higher-purity gallium than 4N:

GaAsGaNGaPInGaAs

Optoelectronics

Similarly, gallium-containing compounds power many light-emitting and light-sensing devices:

LEDsLaser diodesPhotodetectorsSolar cells
