Quartz is a physical property and chemical properties are very stable mineral resources, the crystal is a triad of oxide minerals, that is, low temperature quartz (a-quartz), is the most widely distributed mineral minerals in a mineral species. The generalized quartz also includes high temperature quartz (b-quartz). Stone block, also known as silica, is mainly the production of quartz sand (also known as silica sand) of raw materials, but also quartz refractory materials and ferrosilicon raw materials.
Quartz chemical formula for SiO2, often contain a small amount of impurities such as Al2O3, IMO ,, CaO, MgO and so on. It has many types. Ceramics for the daily use of quartz, quartz sand, quartzite, sandstone, silica, opal, diatomaceous earth, rice shell ash is also rich in SiO2. Quartz appearance is often white, milky white, Quartz gray translucent state, Mohs hardness of 7, section with glass luster or fat luster, the proportion varies by crystal, change between 2.22-2.65.
Quartz is a non-plastic material, and its clay in the high temperature generated mullite crystal to give porcelain higher mechanical strength and chemical stability, and can increase the translucent body, is the preparation of white glaze good raw materials.
In the period of the Republic of China, Quartz the Quartz was produced by the city of Sanbao Peng. After the founding of new China, most of the quartz, such as Xingzi, Duchang and Xiushui were used, especially since the 1920s. Glaze in the amount of 10% -30%, should be washed before use, to remove dirt impurities, placed in the kiln high temperature calcination, easy to crush.
Colorless, transparent quartz variants, the Greeks called "Krystallos", meaning "white ice", they are sure that quartz is durable and sturdy ice. Ancient Chinese people think that the mouth with cold crystals can quench thirst.
Quartz is one of the most widely distributed minerals on the surface of the earth, and its use is quite extensive. Far in the Stone Age, people use it to produce stone axes, Quartz stone arrows and other simple production tools to hunt food and fight the enemy. Quartz glass can be used as standard frequency; made after melting glass, can be used for the production of optical instruments, glasses, glass tubes and other products; can also do precision instruments of bearings, grinding materials, glass ceramics, etc. Industrial raw materials.
Quartz crystal contains small bubbles or liquid filling cracks, will produce rainbow through the interference light, can be made of fine jewelry. Napoleon's wife Empress Josephine (Empress Josephine) has a dazzling collection of precious stones, is made of rainbow quartz jewelry.
Quartz is a kind of mineral which is easy to become liquid when heated or pressed. Is also quite common rock mineral, in the three major types of rocks are there. Because it crystallizes very slowly in igneous rocks, it usually lacks a complete crystal face, mostly filled in the other first crystallized rock mineral.
Quartz is the quartz content of up to 94%, quartz crystal is the natural hardness of diamond after the natural minerals, the surface hardness can be up to Mohs hardness of 7.5, much larger than the kitchen used in the knife and other tools, The
Quartz is made under vacuum conditions in the case of a dense, Quartz non-porous composite material, the quartz surface of the kitchen acid and alkali have excellent resistance to corrosion, the daily use of liquid substances will not penetrate its internal, long time on the surface Of the liquid only with water or clean and bright cleaning agent can be wiped with a rag, if necessary, can be used to scratch the surface of the blade retentive.
Quartz glossy bright surface is after more than 30 complex polishing process, will not be blade shovel scratches, will not penetrate the liquid material, will not produce yellowing and discoloration and other issues, the daily cleaning just rinse with water Can be easy. Even after a long period of use, the surface is also the same as the new table with the bright, no maintenance and maintenance.
Quartz surface smooth, Quartz flat and no scratches stay, dense non-porous material structure makes the bacteria nowhere to hide, can be in direct contact with food, safe non-toxic. Quartz uses a selection of natural quartz crystal minerals, the SiO2 content of more than 99.9% or more, and in the manufacturing process to purification, the raw materials do not contain any possible lead to radiation of heavy metal impurities, 94% of the quartz crystal and other resin additives Making the quartz without the risk of radiation pollution.
