Zinc is specified as below:
Aluminum doped zinc oxide (AZO) films are prepared by rf magnetron sputtering on glass or Si substrates using specifically designed ZnO targets containing different amount of Al2O3 powder as the Al doping source.
The structural, electrical, and optical properties of the AZO films are investigated in terms of the preparation conditions, such as the Al2O3 content in the target, rf power, substrate temperature and working pressure.
The crystal structure of the AZO films is hexagonal quartzite. The orientation, regardless of the Al content, is along the c axis perpendicular to the substrate.
The doping concentration in the film is 1.9 at.?% for 1 wt?% Al2O3 target, 4.0 at.?% for 3 wt?% Al2O3 target, and 6.2 at.?% for 5 wt?% Al2O3 target.
The resistivity of the AZO film prepared with the 3 wt?% Al2O3target is ~ 4.7Ã?10-4 O?cm, and depends mainly on the carrier concentration.
The optical transmittance of a 1500-Ã?-thick film at 550 nm is ~ 90%. The optical band gap depends on the Al doping level and on the microstructure of the films, and is in the range of 3.46?3.54 eV. The optical band gap widening is proportional to the one-third power of the carrier concentration.

Rising prices of other metals, such as copper and nickel, make zinc a more attractive alternative.
While India, Brazil, and South Africa are significant producers of Zinc ore, Nigeria's estimated reserves of untapped Zinc ore are 6 million tons. Zinc ore is found in Cross River, Kaduna, Kebbi and Niger states. Zinc ore in Nigeria is commonly found in deposits, erosion deposits, and minerals transported by water.
Commodity 1 provides Zinc ore directly from the mine site to the global market. There are no middlemen involved, only our staff on the ground. We strive to organize smooth and transparent transactions. We believe in building long-term relationships with our customers. We aim to be our customer's Zinc ore supplier. We offer the best prices for our buyers.

It is essential to know that zinc ore is a radioactive mineral. The level of radioactivity in zinc ore depends on the thorium and
content. Zinc ore containing high levels of thorium and
must be handled carefully.
Zinc ore composition varies slightly based on the source and what region of Nigeria it is collected. We encourage buyers to ask for a free sample for their composition analysis and evaluation of ready-to-ship material. Samples are free, but buyers should arrange to pick up a free piece with a courier service.
