Product introduction:

National standard palladium powder, palladium content is more than 99.95% sponge palladium powder. It's sold in one gram Palladium is a silver white transition metal, which is soft, has good ductility and plasticity, and can be forged, calendered and drawn. The bulk metal palladium can absorb a large amount of hydrogen, making the volume significantly swell, become brittle and even break into pieces. At room temperature, 1 volume of sponge palladium can absorb 900 volumes of hydrogen, 1 volume of colloidal palladium can absorb 1200 volumes of hydrogen. When heated to 40-50 ℃, most of the absorbed hydrogen is released. It is widely used as a gas reaction, especially as a catalyst for hydrogenation or dehydrogenation. It can also be used to make resistance wires, clock alloys, etc. Melting point: 1554 ℃ Boiling point: 2970 ℃ Specific heat: 244j Density: 12.02g/cm3 (20 ℃) Mohs hardness: 4.75 Palladium is an indispensable key material for aerospace, aviation, navigation, weapons, nuclear energy and other high-tech fields as well as automobile manufacturing industry. It is also an investment variety that cannot be ignored in the international precious metal investment market. Palladium chloride is also used for electroplating; palladium chloride and its related chlorides are used for cyclic refining and as a source of pure sponge palladium by thermal decomposition. Palladium monooxide (PDO) and palladium hydroxide [PD (OH) 2] can be used as the sources of palladium catalysts. Sodium tetranitropalladinate [na2pd (NO3) 4] and other complex salts are used as the main components of electroplating solution. Palladium is mainly used as catalyst in chemistry; palladium is fused with ruthenium, iridium, silver, gold, copper and other alloys to improve the resistivity, hardness and strength of palladium, which is used for manufacturing precision resistance, jewelry and other accessories. The most common and marketable alloy for palladium jewellery is palladium Jewelry palladium is 90%. The purity of palladium here is 99.95%. It is a national standard palladium powder.
