Ru

1. Introduce – Ruthenium is often found in nature alongside other platinum group metals and is commercially obtained from pentlandite (a sulfide of iron and nickel) containing small amounts of Ru – As a platinum group element, it has a high melting point (2,334°C) and boiling point (4,150°C), giving it excellent high-temperature stability – It is a relatively unreactive metal that does not react with oxygen at room temperature and is insoluble in most acids and aqua regia at temperatures below 100°C – Due to its excellent wear resistance and electrical conductivity, whe...
