White metal<\/a> looks attractive, which is especially evident when comparisons are made with yellow, gray. When making pure silver jewelry, it is impossible to achieve this effect. The color of the items will always be different from white. To improve the external qualities, a method involving the creation of a coating of another metal is used. This is . Rhodium plating<\/a> silver. This method makes it possible to improve decorations<\/a> by a number of parameters: increase hardness, increase resistance to mechanical damage, etc. As a result, the demand for such products increases manifold.<\/p>\n\n\n\n

What is rhodium-plating silver jewelry and what is rhodium, which is coated silver<\/h2>\n\n\n\n

Rhodium plating is a way of improving the properties of metals that are not distinguished by their attractiveness and hardness. A thin film, a protective coating, is created on the object. In this process they use metal<\/a> rhodium. It is expensive (several times more expensive than gold in costs<\/a>), and therefore are not used in the production of jewelry. Their cost would be unreasonably high. For this reason rhodium is most often used to create a coating layer. It is a platinum group metal: Rh, atomic number - 45 (refers to the 9th group of elements).<\/p>\n\n\n\n

\n

Note: Rhodium is specifically used for plating jewelry because of its high reflection coefficient of electromagnetic rays representing the visible part of the spectrum (it reflects up to 80% of radiation).<\/p>\n<\/blockquote>\n\n\n\n

Rhodium and radium: not to be confused<\/h2>\n\n\n\n

If we compare articles of pure Ag and jewelry that have been coated with metal by rhodium-plating, the difference will be obvious - the latter always looks more attractive. However, when studying this issue, some information about rhodium-plated silver comes into view. It should not be confused with rhodium-plated silver. These are different concepts, which imply the use of different metals.<\/p>\n\n\n\n

Dangerous radium and the history of its discovery. Where is it used<\/h3>\n\n\n\n

Radium is a radioactive metal. It has a high production cost (due to the difficulty of obtaining it) - tons of components (coal, water, etc.) are needed to produce microscopic doses. The element of Mendeleev's table Ra was discovered over a hundred years ago by Marie Curie. The woman scientist was the first in the history of science to receive the Nobel Prize twice for her discoveries.<\/p>\n\n\n\n

Maria Curie was the first to introduce the concept of \"radioactivity. The term \"radiation\" began to be used on the wave of popularity of the poetry of Mickiewicz, who organized the \"Radiation Society. Mary was his admirer. The term \"radioactivity\" is based on radius, which means \"ray\" in Latin. The woman scientist discovered that there was another element with stronger radiation than uranium. The assumption was made on the basis of a study of the properties of the tar dip from the mine. It did not contain any of the chemical elements discovered at the time. Thus began the study of the new metal.<\/p>\n\n\n\n

After its discovery, radium was widely used for a variety of purposes:<\/p>\n\n\n\n
