Platinum (Pt)
Platinum (Pt)
Produced mostly from copper ore, nickel ore, and gold ore, platinum is resistant to heat and corrosion by other chemicals. In chemical reactions, it is used as a catalyst since it accelerates the reaction without changing itself. It is also used in catalytic converters to control exhaust gases because it converts harmful substances from automobiles into harmless compounds.

Palladium (Pd)
Palladium (Pd)
Palladium is a rare element and transition metal belonging to the platinum group, and has properties similar to those of platinum. It is glossy, resistant to corrosion, and bonds well with hydrogen. For this reason, it is used widely in jewelry and dental alloys, in addition to being jointly used with platinum as an automotive catalyst. LS MnM produces 400g palladium ingots with a purity of 99.9% or higher and palladium sponges with a purity of 99.95% or higher.

Crude Rhodium (Crude Rh)
Crude Rhodium (Crude Rh)
Crude rhodium is a raw material for rhodium, which purifies nitrogen oxides from automobile exhaust. The after-leaching solution generated during the production of LS-Precious Sand contains a 1 to 3 ppm level of Rh. This extremely small amount of Rh is substituted and refined to be turned into crude rhodium in the form of cake. With 1 to 2% in Rh content, our crude rhodium is mainly used as a catalyst for exhaust purification and chemical reactions.
