Not everything is worth gold, so says an old saying. And that is an absolute truth, yellow metal is not the most wanted planet on earth as many think. It is another that looks more like silver and is related to the environment. Do you know what that is? Here's the answer to the question.
The metal that is more valuable than gold is palladium. Currently, that item is worth more every day on the world market and by 2019 its price has risen by 40%, which is far from the limit. Its price today already exceeds $ 1,800 per ounce, compared to $ 1,500 per ounce of gold. It is projected that by the end of 2019 its price will exceed $ 2,000, says Faye Weaver.
We go to the old periodic table.This says Palladium: It is a chemical element of atomic number 46 placed in group 10 of the periodic table of elements. Its symbol is PD. It is a transition metal of platinum group, soft, ductile, malleable and not very abundant. Chemically it resembles platinum and is extracted from some copper and nickel mines.
But what is its use and why is it related to the environment? Palladium is used in the production of exhaust gas catalysts for gasoline engines, and as larger countries pay more and more attention to the environment, the demand for this metal continues to grow day by day, says Ole Hansen, head of the Strategy Department the Saxo Bank commodity market, to the Sputnik agency.
"There can be no maximum price for palladium as such until we reach a level where it is more appropriate to use other metal, such as platinum, or until a slowdown in the global economy has led to a decrease in demand for new cars," adds expert Hansen. .
Its silver color and lack of it have caused palladium to be considered precious metal since ancient times, but what makes it so valuable over its appearance are its properties.
And it is that in contact with air it does not oxidize, it is soft and malleable, it is a metal of a less dense platinum group and has the lowest melting point, and, very surprisingly, it can absorb huge molecular hydrogen (H2) quantities of room temperature.
True, this last feature is one that largely makes it an ideal candidate for use in vehicle catalysts, as it can absorb up to 900 times more volume in molecular hydrogen.
Has a role in electronics
Similarly, palladium applications go beyond its use as a central element in the latest generation catalytic converter for vehicles.
In consumer electronics is also a very popular element for its versatility. The industry has provided several applications, but one of the most relevant is to use, usually in silver alloy, in the electrodes of multilayer ceramic capacitors. A capacitor is an electrical component that is capable of storing potential energy in the form of an electric field.
Palladium is also often used, usually in nickel alloy, as a coating on the contact areas between electrical components. Another application of this chemical element is welding panels, especially those used in jewelry, for their strength, strength and durability.
