Basic Info of Mercury(II) Selenide

What is Mercury(II) Selenide?

The chemical formula of mercury selenide is HgSe. Molecular weight 279.55. Gray-black square crystal. Toxic! Specific gravity 8.266. Sublimation in nitrogen, carbon dioxide atmosphere or vacuum heating to about 600 ° C, the sublimation is purple-black. Insoluble in water, soluble in ammonium selenide solution. It is obtained by adding dilute mercuric chloride solution dropwise to saturated hydrogen selenide solution or heating stoichiometric amounts of mercury and selenium to 550-600 ℃ in a sealed tube. is a semiconductor material. Used in the manufacture of solar cells, thin film transistors, infrared detectors and ultrasonic amplifiers.

Mercury(II) Selenide Uses

Mercury Selenide, as a semi-metallic material, is used in the manufacture of solar cells, thin film transistors, infrared detectors and ultrasonic amplifiers. It is also used to make Hall-effect high-strength films and analytical reagents. Currently, there are no patents and literature reports on the use of HgSe as a photocatalyst for the degradation of dye pollutants.

Production Method of Mercury(II) Selenide

  1. Add the dilute solution of HgCl2 dropwise to the saturated aqueous H2Se solution under the condition of isolation of air to obtain the HgSe precipitated product. Note that HgCl2 should not be excessive, and high concentration of HgCl2 solution should not be used, otherwise HgCl2·2HgSe will be precipitated. 2. Add HgCl2 into the strong ammoniacal NaCN solution according to the stoichiometric ratio, and then add an equivalent amount of SeO.
  2. After the mixed solution was filtered, SO2 gas was introduced. During the whole reaction process, keep the solution alkaline Chemicalbook to prevent the red selenium from precipitating out. The endpoint of the reaction can be determined by the decrease in the rate of SO2 uptake. After the reaction, the black HgSe was suction filtered, washed with a dilute NaCN solution containing ammonia, then washed with distilled water, and finally dried in a desiccator filled with P2O5.
  3. Put Hg and Se into a closed high-pressure container according to the stoichiometric ratio, carry out the reaction at a temperature of 550-600 ℃, and then sublime and purify the product in a pure N2 gas stream at 600-650 ℃ to obtain pure HgSe products.

Great company! thanks from Australia for good product quality, correct product, good customer service using chat.. delivery speed was ok, via FedEx. the Alibaba App finally makes it safer, so good companies like Shandong Zhi Shang can do business with us, I don't have to worry now with Alipay. Everything is safe for me now, I can't go wrong. frst time payments can just use card, the seller never knows your details, only Alibaba does the payment, so the risk is gone, delivery on time is guaranteed, and because the seller can't see your card details, scammers can't use this system, only good companies that do the right thing can make money here. it really is a much better system now.

I general, was very satisfied with the supplier. Basic analyzes (m.p.. FTIR) of the product in our facility confirmed its high quality. Further analyzes are planned, but due to the COVID-19 pandemic, most laboratories in Slovenia are closed.
