Our company have been developing high-quality CVD-ZnSe synthesis technology since 1983 We have published more than 120 works on subjects, related to the ZnSe production, have been granted 4 patents in Russia and we also possess 5 know-hows. Our achievements now make it possible for us to serve the production needs of IR, high purity (99.999%) ZnSe for us for all intents and purposes. We deliver Zinc Selenide (ZnSe) scrap in various sizing and volumes.
