Quartz Is One Of The Minerals On The Surface Of The Earth

Jul 28, 2017

Quartz is a kind of mineral resource which is very stable in both physical and chemical properties, and the crystal belongs to the oxide minerals of the three-party crystal system, that is, low temperature quartz (a-quartz), which is one of the most widely distributed mineral species in quartz group. Quartz The generalized quartz also includes high temperature quartz (b-quartz). Quartz block also known as silica, mainly the production of quartz sand (also known as silica sand) raw materials, but also quartz refractories and fired ferrosilicon raw materials.

Quartz chemical type for SiO2, often contains a small amount of impurities such as $literal, IMO, Cao, MgO and so on. It has many types. Daily-use ceramic raw materials used in quartz, quartz sand, quartzite, sandstone, silica, egg white stone, diatomite, rice crust ash is also rich in SiO2. Quartz appearance is often white, ivory, Quartz gray translucent state, MO's hardness is 7, broken mask glass luster or fat luster, Quartz the proportion due to the crystal type and change in 2. 22-2. Between 65.

Quartz is a non malleable material, and its mullite crystals with clay in high temperature endow porcelain with high mechanical strength and chemical stability, and can increase the translucency of the body, and is a good raw material for preparing white glaze.

During the period of the Republic of China, the use of the city of the triple gem canopy produced quartz, the new Chinese after the founding of most of the stars, Douchang, Xiushui and other places of quartz, especially since the 20, the dosage increased dramatically. Glaze with a volume of 10%-30%, Quartz should be washed before use, remove dirt impurities, placed in the kiln High-temperature calcination, easy to crush.

A colorless, transparent quartz variant, called "Krystallos" by the Greeks, means "white ice", convinced that quartz is a durable and solid ice. Ancient Chinese thought that the cold crystals in their mouths would quench their thirst.

Quartz is one of the most widely distributed minerals on the Earth's surface, and its use is quite extensive. In the Stone Age, people used it to make simple tools such as stone axe, Quartz Stone arrow and so on to hunt food and fight the enemy. Quartz clock, electronic equipment as the standard frequency, the fused glass, can be used for the production of optical instruments, glasses, Quartz glass tubes and other products, but also can do precision instruments bearings, abrasive materials, glass ceramics and other industrial materials.

Quartz crystals containing small bubbles or liquid filling cracks, will be through interference light produced rainbow, can be made into exquisite jewelry. Napoleon's wife, Queen Josephine (Empress Josephine), Quartz has a dazzling collection of gems, a jewel made of rainbow Quartz.
