Is cadmium selenide harmful to human body?
What is Cadmium selenide?
Cadmium selenide has a molecular formula of CdSe and a molecular weight of 191.36. It is a grayish-brown or red crystal. Cadmium selenide can be prepared by co-heating metal cadmium with hydrogen selenide. It can also be obtained by directly combining the metal cadmium with selenium at high temperatures. Hydrogen selenide gas is introduced into cadmium chloride or cadmium sulfate solution to precipitate cadmium selenide, and the cadmium selenide product can be obtained through suction filtration, washing, and drying.

More about Cadmium selenide
Melting point: 1350℃
Density: 5.81g/cm3
Appearance: grayish brown or red crystals.
Solubility: insoluble in water
Toxicity of Cadmium selenide Powder
Cadmium and its compounds are mainly absorbed through the respiratory tract and digestive tract. It can enter the blood through alveoli, and 90%~95% of cadmium in blood exists in red blood cells and combines with hemoglobin. Cadmium entering tissues and cells is mainly distributed in the kidney, liver, and lungs. Cadmium can enter fetal tissue through the placental barrier. Chronic cadmium poisoning mainly causes renal damage, mainly renal tubular lesions. In severe cases, chronic renal failure and osteomalacia, and osteoporosis may occur.
Cadmium is a kind of micro-toxic. Among cadmium compounds, cadmium sulfide and cadmium selenosulfonate belong to low toxicity, while cadmium oxide, cadmium sulfate, cadmium chloride, and cadmium nitrate belong to medium toxicity.
Acute poisoning of cadmium is not common. Ingestion of cadmium compounds can also cause acute poisoning of the human body. After the incubation period (mercury has a longer and more obvious neurotoxic incubation period), the body will have acute gastrointestinal irritation symptoms, which lead to general fatigue, muscle aches, collapse, etc., mainly because cadmium pretends to be calcium.
The chronic toxicity of cadmium usually shows renal dysfunction at first, and then the most obvious symptom is bone, that is, "painful disease." If cadmium is not discharged in time, there will be further harm. However, most people can't survive the "painful disease" and die.
Applications of Cadmium selenide Powder
CdSe material is transparent to infrared (IR) light, and its application in photoresistors and windows of instruments using infrared light is limited. The material also has high luminous performance. CdSe is a component of orange cadmium pigment.
Price of Cadmium selenide Powder
Cadmium selenide powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Cadmium selenide powder. A large amount of large amount will be lower. The price of Cadmium selenide powder can be found on our company's official website.
