White gold is known as platinum is a chemical element and a pt symbol in the periodic table. It is classified as a transition metal. Its physical properties are hardness, magnetism, tensile strength, 125-245 Gb, a 230 Gpa, Its melting point is 17680c.
Plata is a Spanish word meaning “small silver”. It is a precious metal, it is white gray. Platinum is stronger than iron but its elasticity is gold.
The advantage of this metal strength and non-rust, and has the ability to maintain luster when exposed to air, and this is because platinum does not react with oxygen, and is not affected by acids that melt other metals.
Platinum is melted using a mixture of nitric acid and hydrochloric acid, combined with arsenic and silicon, and white gold is worth more than gold, twice the value of gold.
When did platinum (white gold) be discovered?
In 1557, the Italian scientist Julius Scaliger discovered the metal for the first time. In 1750 the Spaniards attempted to discover large quantities of platinum, but at the beginning of its discovery it was cheap because the world had not discovered its value at the time. But when the world and the specialists realized The benefits of this metal and its multiple uses in the fields of life began to spread widely and this led to an increase in demand for it and thus increased its price ..
Fields of use of platinum (white gold):
Platinum is used in many fields, used by chemists in the laboratory to conduct some scientific experiments, such as dissolving samples with different acids, and in the work of panels and thin wires, and also enters the manufacture (catalytic converter), which is in the exhaust of cars.
The common use is his entry into the jewelry industry because of his strength and firmness, and may enter the dental and surgical instruments industry.
There are two types of white gold, the first type is derived from gold and other minerals such as silver, palladium and copper, and the second type is made of platinum itself without mixing with other elements (pure platinum).
As for the first type, it is not permissible for men to adorn themselves with it, and zakaah is obligatory on them as is required in gold and silver. The second type is pure white gold, which can be worn by men, but without exaggeration.
Can we distinguish between pure white gold and platinum?
Yes, this can be done by means of a zero test, by bringing a piece of white gold and trying to scratch it. If it is easily scratched, it is white gold or by heating a metal until it turns into flame and leaves it to cool. If it turns dark, If it does not change color it is platinum.
Some women are reluctant to buy yellow gold and their tendency to white gold, to keep up with the current fashion, or to have more beauty and attractiveness than yellow. This may be due to the culture of society itself or to the personal taste of each woman.
