The main purpose

Palladium is an indispensable key material in high-tech fields such as aerospace, aviation, navigation, weapons and nuclear energy, as well as in the automobile manufacturing industry. It is also an investment product that cannot be ignored in the international precious metal investment market.

Palladium chloride is also used in electroplating; palladium chloride and its related chlorides are used in recycling refining and as a source of pure sponge palladium produced by thermal decomposition. Palladium monoxide (PdO) and palladium hydroxide [Pd(OH)2] can be used as sources of palladium catalysts. Sodium tetranitropalladium [Na2Pd(NO3)4] and other complex salts are used as the main components of the electroplating solution.

Palladium is mainly used as a catalyst in chemistry; palladium is melted into alloys with ruthenium, iridium, silver, gold, copper, etc., which can improve the resistivity, hardness and strength of palladium, and is used to make precision resistors and jewelry. The most common and most valuable palladium jewelry alloy is palladium.

Mainly used to make catalysts, but also to make dental materials, watches and surgical instruments.
