Gallium doped Zinc Oxide
Gallium doped Zinc Oxide (atomic symbol: Ga, atomic number: 31) is a Block P, Group 13, Period 4 element with an atomic weight of 69.723.The number of electrons in each of Gallium’s shells is 2, 8, 18, 3 and its electron configuration is [Ar] 3d10Â 4s2Â 4p1. The gallium atom has a radius of 122.1 pm and a Van der Waals radius of 187 pm.Â
Gallium was predicted by Dmitri Mendeleev in 1871. It was first discovered and isolated by Lecoq de Boisbaudran in 1875. In its elemental form, gallium has a silvery appearance.Â
Gallium doped Zinc Oxide is one of three elements that occur naturally as a liquid at room temperature, the other two being mercury and cesium. Gallium doped Zinc Oxide does not exist as a free element in nature and is sourced commercially from bauxite and sphalerite. Currently, gallium is used in semiconductor devices for microelectronics and optics.
The element name originates from the Latin word ‘Gallia’, the old name of France, and the word ‘Gallus,’ meaning rooster.
Zinc:
Zinc (atomic symbol: Zn, atomic number: 30) is a Block D, Group 12, Period 4 element with an atomic weight of 65.38.
The number of electrons in each of zinc’s shells is 2, 8, 18, 2, and its electron configuration is [Ar] 3d10 4s2. The zinc atom has a radius of 134 pm and a Van der Waals radius of 210 pm. Zinc was discovered by Indian metallurgists prior to 1000 BC and first recognized as a unique element by Rasaratna Samuccaya in 800. Zinc was first isolated by Andreas Marggraf in 1746. In its elemental form, zinc has a silver-gray appearance.
It is brittle at ordinary temperatures but malleable at 100 °C to 150 °C. It is a fair conductor of electricity, and burns in air at high red producing white clouds of the oxide. Zinc is mined from sulfidic ore deposits.
It is the 24th most abundant element in the earth’s crust and the fourth most common metal in use (after iron, aluminum, and copper). The name zinc originates from the German word “zin,” meaning tin.

Copper Indium Gallium Selenide Description
Copper Indium Gallium Selenide Powder (CIGS) for solar energy applications is a p-type or absorber layer material. CIGS-based photovoltaic cells (PV Cells) for solar energy are fabricated from a positively charged or p-type CIGS layer underneath a negatively charged or n-type layer.
The p-type layer can be produced by thin film deposition of a Gallium doped Copper Indium Selenide (CIGS) Nanopowder sold under the Nanochemazone Solar Energy group. Most CIGS-based PV solar cells are produced from thin film deposition of CIGS using sputtering techniques.
Nanochemazone produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available.

They are extremely hard, brittle, refractory ceramic materials with metallic electrical conductivity. They appear as brown-gray powders, which are usually processed by sintering.
Being important cermet materials, tantalum carbides are commercially used in tool bits for cutting applications and are sometimes added to tungsten carbide alloys.
The melting points of tantalum carbides peak at about 3880 °C depending on the purity and measurement conditions; this value is among the highest for binary compounds. Only tantalum hafnium carbide may have a slightly higher melting point of about 3942 °C, whereas the melting point of hafnium carbide is comparable to that of TaC.
Tantalum Carbide Application:
Tantalum Carbide Powder Applications
1. Tantalum carbide is often added to tungsten carbide/cobalt (WC/Co) powder attritions to enhance the physical properties of the sintered structure. It also acts as a grain growth inhibitors preventing the formation of large grains, thus producing materials of optimal hardness.
2. It is also used as a coating for steel molds in the injection molding of aluminum alloys. While providing a hard, wear-resistant surface, it also provides a low friction mold surface.
3. Tantalum carbide is also used in the production of sharp instruments with extreme mechanical resistance and hardness.
4. It is also used in tool bits for cutting tools.
Tantalum carbide is widely used as a sintering additive in ultra-high temperature ceramics (UHTCs) or as a ceramic reinforcement in high-entropy alloys (HEAs) due to its excellent physical properties in melting point, hardness, elastic modulus, thermal conductivity, thermal shock resistance, and chemical stability, which makes it a desirable material for aircraft and rockets in aerospace industries.
Nanochemazone specializes in producing high purity Tantalum Carbide Powder with the smallest possible average grain sizes for use in the preparation of pressed and bonded sputtering targets and in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low-Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Powders are also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also produce very high surface areas. Our standard powder particle sizes average in the range of - 325 mesh, - 100 mesh, 10-50 microns, and submicron (< 1 micron). We can also provide many materials in the nanoscale range.
