Cadmium Hydroxide Powder Description:
Cadmium Hydroxide Powder (CAS: 21041-95-2) is a white amorphous powder. It can absorb carbon dioxide in the air. Cadmium Hydroxide Powder is soluble in dilute acid, ammonium hydroxide, and ammonium chloride solution, slightly soluble in sodium hydroxide solution, almost insoluble in water, toxic, and possibly carcinogenic.
Cadmium hydroxide can be used to prepare nickel-cadmium batteries, prepare other cadmium salts, and metal surface treatment and gas chromatography analysis. Stanford Advanced Materials (SAM) is a leading supplier of Cadmium Hydroxide across the world.

Cadmium hydroxide Powder FAQs
Q1: What is Cadmium Hydroxide Powder?
Answer: Cadmium Hydroxide Powder is a chemical compound with the formula Cd(OH)₂, consisting of cadmium and hydroxide ions. It typically appears as a white or off-white crystalline powder.
Q2: What are the common applications of Cadmium Hydroxide Powder?
Answer: It is used in electroplating, pigment production, battery manufacturing (particularly in nickel-cadmium batteries), and as a laboratory reagent.
Q3: How is Cadmium Hydroxide Powder synthesized?
Answer: It can be synthesized by reacting cadmium salts (such as cadmium sulfate or cadmium chloride) with an alkaline hydroxide (such as sodium hydroxide or potassium hydroxide) in an aqueous solution, precipitating Cadmium Hydroxide as a solid.
