wallpapers News 2020-12-23
Tin powder is gray-green powder with a melting point of 231.88°C. The boiling point is 2270°C. The relative density is 7.28. It is soluble in concentrated hydrochloric acid, sulfuric acid, aqua regia, concentrated nitric acid and hot caustic alkali solution, and slowly dissolves in cold dilute hydrochloric acid, dilute nitric acid and hot dilute sulfuric acid. Cold caustic alkali solution dissolves more slowly in acetic acid. It is stable in air, but tin powder is easier to oxidize, especially in moist air. Materials used in the electronics industry, used as high-purity reagents.
Storage method
1. It should be stored in a cool, ventilated and dry warehouse.
2. It cannot be stored and transported together with inorganic acids, strong alkalis, edible raw materials and flammable materials. Avoid rain and hot sun during transportation.
Metal tin is mainly used to make alloys.
Tin and sulfur compound-tin sulfide, its color is similar to gold, often used as a golden pigment.
The compound of tin and oxygen-tin dioxide. Tin is not oxidized in the air at room temperature, but becomes tin dioxide when heated by strong heat. Tin dioxide is a white powder that is insoluble in water and can be used to make enamel, white glaze and opal glass. Since 1970, people have used it to prevent air pollution-car exhaust often contains toxic carbon monoxide gas, but under the catalysis of tin dioxide, most of it can be converted into carbon dioxide at 300°C.

Tin ware has a long history, dating back to 3700 BC. In ancient times, people often put tin blocks at the bottom of wells to purify water. In the Japanese court, the carefully brewed imperial wine was made of tin ware as the vessel for wine. It has the same color of storing tea, warm in winter and cool in summer when the wine is served, and the tradition is honest and clear. The tin teapot makes tea especially fragrant, drinking with a tin cup is refreshing and refreshing, and the flower arrangement in the tin bottle is not easy to wither. In the late 18th and early 19th centuries, tin was used to make fresh-keeping cans.
The material of the tinware is an alloy, in which the pure tin content is over 97%, and it does not contain lead, which is suitable for daily use. The peaceful and silky characteristics of pewterware, the noble and elegant shape, and the long-lasting new luster, have always been favored by the nobles, and become a symbol of classical culture in Europe.
Tin is the fourth precious metal behind platinum, gold and silver. It is luster, non-toxic, not easy to oxidize and discolor, and has good sterilization, purification and freshness preservation effects. It is often used in food preservation and anticorrosive film on the inner layer of cans.
Tin is a soft metal with a low melting point and strong plasticity. It can have a variety of surface treatment processes, and can be made into a variety of styles of products, including traditional and elegant European wine sets, candle holders, noble and generous tea sets, and even impressive vases and exquisite table decorations. The styles are all comparable to shiny silverware. Tinware has been popular all over the world for its elegant appearance and unique functions, and it has become people's daily necessities and good gifts for relatives and friends.
Tin was often used to make bronze in ancient my country. The ratio of tin to copper is 3:7.
