Learn about the Precious Metals in Catalysts and Particle Filters
Platinum is a precious metal that belongs to the group of heavy platinum metals. Its chemical symbol is Pt and its atomic number is 78. Platinum has a silver-white color and is a hard, malleable and malleable metal. Platinum has a density of 21.45 g/cm3 and melts at a temperature of 1768.3 °C.
Rhodium is a silver-white metallic element with chemical symbol Rh and atomic number 45. It belongs to the group of precious metals and is one of the rarest metals found on earth.
Rhodium is an extremely hard and durable metal, with a high melting point of 1964 °C.
Palladium is a metallic element that belongs to the group of light platinum metals. The chemical symbol for palladium is Pd and its atomic number is 46. Palladium has a silver-white color and is a soft and malleable metal. It has a density of 12.02 g/cm3 and melts at a temperature of 1554.9 °C.
Learn to distinguish the different Cores
And how do a catalytic converter and a particulate filter work?
Most automotive catalytic converters have a ceramic core, in the core are the valuable precious metals platinum, rhodium and palladium
The core of the particulate filter is different from the core of the catalytic converter.
The difference between a particle filter and a catalyst is that the particle filter is there to filter out harmful particles in the exhaust gases.
Like the ceramic catalyst, the metallic catalyst cleans the exhaust gases from gasoline-powered vehicles.
You can recognize the metallic catalyst on the metallic core like the picture in the link below
Catalysts are used in many industrial applications, such as bio and natural gas plants, cogeneration plants and industrial and chemical plants. These can be both ceramic and metal catalysts, which also contain interesting amounts of precious metals
