The platinum is a chemical element, commonly known as platinum. Platinum is a natural white precious metal, and only platinum can be called platinum. Platinum is strong, which can be pulled into very thin platinum silk, rolled into extremely thin platinum foil; strength and toughness are also much higher than other precious metals. Even if 1 gram of platinum is pulled into 1.6 kilometers long filament, it will not break. The melting point is as high as 1773.5 ° C. The thermal conductivity is good. The chemical properties are extremely stable, insoluble in strong acid and strong alkali, without oxidation in the air. Platinum does not absorb mercury and has a unique catalytic effect. Because of the excellent performance of platinum, its purposes are very wide. In the jewelry industry, it is mainly used for decorations and crafts. In the chemical industry, it is used to create catalysts for high -grade chemical utensils, platinum, electrodes, and accelerated chemical reactions. Platinum alloy is a material for making the tip of the tap. In addition, platinum has the following uses: 1. Platinum has strong antioxidant power and high melting point, so it is also used to make aerospace uniforms. Platinum, as a catalyst, is widely used in the tail purification device of the car, plays an important role in protecting the environment. 2. Platinum during World War II had very important military uses because it was a good catalyst with high melting point. The U.S. government once banned platinum non -military affairs. 3. No one's skin is allergic to platinum. Platinum can be used as an electrode for electronic pulse regulator, directly inserted into the heart of the human body, and cure patients with arrhythmia. 4. Platinum can also be used to make waterproof watches with a diving depth of 200 meters.
A precious metal element, element symbol PT, is a chemical catalyst commonly used. . Strong ductility, can be pulled into very thin platinum silk, rolled into extremely thin platinum foil; strength and toughness are much higher than other precious metals. Even if 1 gram of platinum is pulled into 1.6 kilometers long filament, it will not break. The melting point is as high as 1173.5 ° C. The performance of thermal conductivity is good The platinum metals include platinum, 钯, 锇, 铑, 铱, and 钌. Platinum ore refers to the general term of platinum -based metal minerals. Among the platinum metals, people are the most familiar and most useful for platinum, that is, platinum. Due to the expensive price, it is commonly referred to as precious metals with gold and silver. The white gold is silver -white when it is pure; metal luster; hardness is 4 to 4.5 degrees; the proportion is 15-19; the melting point is as high as 1173.5 degrees Celsius; it is extended; good conductivity; extremely stable chemical properties (in ordinary acids (in ordinary acids Involved and not oxidized in the air). Platinum is similar to silver, but the latter's hardness (2.5 degrees) and the proportion (10-11) are low, and it is soluble in nitric acid. Thekin, as a precious metal that costs more than gold, has many excellent characteristics, and its purposes are very wide. It is usually used in industrial, jewelry industry, investment (reserve, currency production) and science and technology. In the total demand for the world's platinum, 40% of the manufacture of automotive exhaust gas catalytic converters; 30% for jewelry manufacturing; 25% for investment preservation purchases. In the industrial field, Platinum is usually used in automotive manufacturing, chemical industry, petroleum, natural gas, optical materials, medical, electronics, aerospace and other industries. For example, more than 2 million ounces of platinum used for refining plants around the world each year as catalysts for processing crude oil. However, Platinum is used in large quantities to manufacture automotive exhaust gas catalytic converters to prevent vehicle exhaust gas pollution and protect the environment. Scientists have found that Platinum is a nemesis of exhaust gas discharged by automotive engines. Placing 1.5 to 2 grams of platinum is placed in the automotive exhaust gas purification device, and the nitric oxide oxide, carbon monoxide and toxic hydrocarbons discharged by the car engine can be purified into non -toxic nitrogen, carbon dioxide and water. Japan is one step ahead of this. The anti -automotive exhaust gas pollution method in the United States, Japan and Western Europe hard stipulates that automobiles must install waste gas catalytic converters. This once caused platinum prices to rise from $ 250 per ounce in 1985 to $ 600 per ounce in August 1988. In the United States, the second largest consumer country in the world, the platinum used for automobile manufacturing has reached 60% of its total consumption. The benefits of making jewelery with platinum: ⑴, Platinum natural color is white, without oxidation in the air, does not change color, inlaid jewelry (especially diamonds) in the Platinum seats ; ⑵, Platinum's strength is high, friction resistance, acid -resistant and soluble, not easy to corrodes, the chemical properties are extremely stable, making the gemstone inlaid firmly and not easy to fall off. The color of Platinum and Platinum is not only beautiful, but also more matched with people's skin tone. It is generally believed that the appearance of platinum jewelry is elegant and subtle, and the shiny silver white light exudes a quiet and noble temperament. It has strong decorativeness, sets people in harmony and perfectness, and has a unique charm to people. Seeing that the rich and luxurious people of gold jewelry love the fresh and elegant of Platinum. Therefore, platinum jewelry is particularly loved by ladies. The United States, the United Kingdom, France, Germany, and Japan have always wearing the tradition of platinum jewelry, especially Japan's most prominent. In Japan, the world's largest consumer country, Platinum is mainly used for jewelry industry, accounting for about half of its total consumption.
