White gold

White gold has been known since ancient times as platinum, one of the chemical elements in the periodic table symbolized by the symbol Pt. This element has many advantages that it gains. It is a white gray transition metal. Its tensile strength is high up to 125-245 Gb, its boiling point is 3825c, its melting point is 17680c, and the coefficient is 230 Gpa. The platinum element is stronger than the strength of the iron element, and its elasticity is similar to that of ordinary gold. The Spanish word “Plata” means Small silver, and a platinum and precious metals and has a special place, which made it expensive in the different markets.

History of the discovery of white gold

The discovery of white gold dates back to 1557, when the Italian scientist Julius Scaliger first discovered this element for the first time, and the Spanish discovered more large quantities of this distinctive metal in 1750, when it was initially sold cheaply because its value has not been traded as it is now.

The qualities of white gold

• Great strength, hardness.
• Not affected by the surrounding environmental effects, white gold is rusty and does not lose its brightness over time.
• Resistant to high temperatures and corrosion factors.
• Good resistance to acidic elements that have the ability to affect other metals.
• Its elasticity is good, as it can be dissolved by mixing it with nitric acid and hydrochloric acid.

How to distinguish white gold

White gold can be distinguished by many ways:

• Scratch the piece of gold, if scratched it was white gold.
• Heat the piece of gold so much that it turns into a flame, if turned after the cooling to a dark color was white gold.
• Exposure to some alkaline acids, if melted was white gold.

Uses of white gold

• It is used in the manufacture of jewelry because of its hardness and not affected by climatic factors such as air and rust, and its luster lasts for long periods.
• Contributes to the elimination of toxic gases in nature, when combined with it converts them to nitrogen gas, or water vapor, or carbon dioxide.
• It is used in the field of chemical analysis laboratories in which samples are dissolved when mixed with different acids.
• It is used in the manufacture of slabs and thin wires which are used in many electrical purposes and equipments.
• Helps to analyze and dismantle oil components separately.
• Used in the manufacture of medical teeth and surgical instruments and laboratory, and the manufacture of chemical compounds that have an effect in the treatment of cancers of all kinds.
• Used in the automotive parts industry, where the catalytic converter is inserted into the vehicle exhaust.
