| titleOfInvention | A kind of preparation method of ultra-high purity cadmium selenide polycrystalline material |
| abstract | The present invention relates to a kind of preparation method of ultra-high purity cadmium selenide polycrystalline material, for raw material using the blocky selenium of the high-purity blocky cadmium and purity >=99.999% of purity >=99.999%, constituent cadmium/selenium is 1.0:(1.0~1.03) can be directly used as monocrystal of cadmium selenide growth raw material close to ideal stoichiometric ratio.It selects internal diameter between the tubular electron grade quartz ampoule of 10~Φ of Φ 50mm, and quartz ampoule is horizontally placed at preparation ultra-high purity cadmium selenide polycrystalline material in tube furnace.One step of the method for the present invention cadmium selenide polycrystal powder material preparation process is completed, and soaking time is short, and yield is high, without purifying, thus simple process and low cost, there is the foreground for realizing prepared by ultra-high purity cadmium selenide scale. |
