Zinc Sulfide
Formula: ZnS
Item #: ZI-5940
CAS #: 1314-98-3
EC / List #: 215-251-3
Market Focus: Security Phosphors, High Purity Thin Film Coating, Polycrystalline Ceramics
Other Applications:

Potential applications as a phosphor host, in optical coating, or for infrared window material.


ZnS powder at 1-2 microns is the source material for our tablets and granules for the vacuum evaporation of thin film coatings. Lorad scientists have developed a proprietary method  for sintering zinc sulfide to high density.

It should be noted that we also manufacture a range of very high purity zinc dialky dithiocarbamates, specially purified to be suitable for the chemical vapor deposition of zinc sulfide thin films. Lorad can provide user information to customers relating to the conditions for thin film growth, and the application of these precursors in an aerosol  and conventional CVD source application.

  • Zinc diethyldithiocarbamate
  • Zinc ethylxanthate
