Definition of
Quartz
the german term quartz came to our language as quartz. It’s about a mineral of great hardness and colorless in its natural state, which is formed with silica (a compound made up of oxygen and silicon).
Quartz, widely present in the planet’s crust Landis he anhydrous of the silica. In general terms, one speaks of anhydrous either anhydrous to refer to a substance that does not have water, and to obtain it, different methods must be applied, depending on the case.
The method of obtaining the anhydrous form of a solvent most frequently used is to bring it to a boil with a substance hygroscopic, that is, one that is capable of absorbing moisture from the environment that surrounds it. On the other hand, it is also possible to use alkalis or molecular sieves, such as barium oxide or potassium hydroxide.
Quartz can be found in various kinds of rocks, mixed with titanium, potassium, sodium, lithium, and other substances. In the Mohs scaledeveloped by the German Friedrich Mohs in it XIX centuryquartz has a hardness of grade 7which means that it can scratch glass and ordinary steel.
Depending on the substance with which it is mixed, quartz presents different colors and properties. Among the best known varieties of quartz are the following:
* citrine: it is a stone with a great magnetic capacity, which is believed to be beneficial for fostering creativity, dynamism and enthusiasm, as well as attracting abundance;
* agate: vibration at high frequencies, it is said that it gives us security and firmness through the absorption of negative energies;
* amethyst: This variety of quartz is considered “protective” as it acts as an alert to keep consciousness awake and enhance intuition. It also helps to get rid of negative emotions and calm anger;
* crystal quartz: is one of the most beneficial from this list, since it amplifies and enhances energy and directs it where we want. Many people use it to fight negative energies that prevent them from moving forward in life. Despite its popularity in certain areas, it is also largely unknown in others.
The uses of quartz are multiple. It can be used to make sandpaper, optical instruments, and gems. It is also used in the development of clocks electronics known as quartz watches.
These watches have a piece of this material that, activated through a electric batteryproduces the impulses needed to measure the time at regular intervals. In general, the quartz is carved as a sheet and is placed inside a metal cylinder that protects it. The electricity provided by the battery causes the quartz to vibrate regularly, allowing the temporary measurement to be made.
The history of the quartz watch dates back to the beginning of the 20th century, when J.W. Horton and Warren Morrison manufactured the first specimen in the company’s laboratories Bell Telephone, in North America. watch manufacturing company Seikoof Japanese origin, used his own quartz watch called Quartz Crystal QC-591 in 1964 to time the Tokyo Olympic Games. Three years later the first two bracelet versions appeared, although still in a state of prototype; one of them, also made by Seiko, was the first to reach commercial stores, in 1969.
A quartz glass microbalanceon the other hand, is a device used to measure the mass. The use of this balance is linked to the precise measurement of very small masses.
