Description
ACS reagent, 99%
Linear Formula: ZnSO4 · 7H2O
Application
Zinc sulfate heptahydrate may be used to prepare:
- Zinc tris(thiourea) sulphate (ZTS), a semiorganic nonlinear optic (NLO) material that may be useful in laser fusion experiments and in second-harmonic-generation (SHG) devices.
- Highly pure zinc oxide nanostructures via a precipitation method for use in catalytic reactions.
