Materials buying guides
Practical ways to define requirements, assess evidence and compare commercial terms.
Selling gallium: compare the assay, the buyer specification and the net return
Compare gallium sale and toll-refining offers using exact assay, buyer impurity limits, payable yield, processing costs and net proceeds.
Buying germanium: specify the material before comparing the price
Specify germanium metal, compounds or components before comparing offers. Review assay evidence, sample acceptance, payable content and complete delivered cost.
