Platinum (10% Pt black powder) is a high-purity catalyst widely used in laboratory and industrial applications. In the automotive industry, platinum serves as a key component in catalytic converters, reducing harmful emissions by converting toxic gases like carbon monoxide, nitrogen oxides, and hydrocarbons into less harmful substances such as carbon dioxide, nitrogen, and water vapor. In the chemical industry, it acts as a catalyst in processes like the production of nitric acid, silicone, and benzene. This powdered form is essential in the electronics sector for manufacturing hard drives, fiber optic cables, and LCD displays due to its excellent conductivity and corrosion resistance. In the medical field, platinum is used in devices like pacemakers and chemotherapy drugs, particularly cisplatin and carboplatin, which are effective in treating various cancers. Additionally, platinum is highly valued in jewelry making for its durability, luster, and hypoallergenic properties.
