NEXTECK has been engaged in the supply, refinement and recovery business of high purity Indium, Gallium and Selenium for over the past few decades. We are specialized in offering standard Indium, Gallium and Selenium for CIGS thin film industry.
You can count on us from the virgin material supply to the recovery of
In/Ga/Se from CIGS scrap. We welcome your consultation for the recovery
from CIGS scrap.
Our main indium products include high purity indium ingot (≧99.995%), Indium bead (≧0.1mm), Indium-thread, indium flake
(pad) and so on. Our indium product are mainly produced through recovery
of slag (stone), remnant ITO target, dross, cleansing liquor and any
materials contains indium.
Indium granules 4N/5N
Gallium 4N/6N
