Quartz is a mineral resource with very stable physical and chemical properties. Quartz stone is an abbreviation for the plates produced by current quartz stone plate manufacturers. Because the main component of the plate is more than 93% quartz, it is called It is quartz stone.
Quartz stone has many variants due to the difference in particle size, color, inclusions, etc.: ①The crystalline quality includes: colorless and transparent crystal; purple amethyst (commonly known as amethyst); smoke yellow, smoke brown to nearly black citrine, Smoky crystal or smoky crystal; light yellow, transparent citrine; rose red rose quartz (commonly known as hibiscus stone); milky white milk quartz. Aventurine that flashes like spots due to scaly inclusions such as hematite or mica. ② Cryptocrystalline variants include chalcedony (chalcedony) composed of fibrous crystallites; agate of colloidal origin; tiger eye stone made of quartz replacing fibrous asbestos. ③ Cryptocrystalline variants are composed of granular crystallites, often containing mixtures of other minerals, opaque, mainly flint, gray to black (commonly known as flint). Jasper is dark red or green-yellow, cyan, and other colors due to iron oxide impurities. Large quartz crystals are mainly produced in pegmatite geodes; massive ones are often produced in hydrothermal veins; granular quartz is the main mineral component of many rocks such as granite, gneiss, and sandstone. In addition to crystals and agates, which are used as gemstones or craft materials, relatively pure general quartz is used in large quantities as glass raw materials, abrasive materials, and silicon refractory materials. Impure quartz is an important building material.
Quartz stone has the characteristics of high hardness, pollution resistance, high-temperature resistance, and no radiation. Quartz stone is favored by people in the current decoration industry. Why does quartz stone have these characteristics? Let us understand together.
Diamonds have the highest hardness among natural minerals in nature. Quartz is second only to diamonds. The content of quartz in quartz stone is extremely high. The knives used in the kitchen will not damage the quartz stone. Quartz stone is a dense and non-porous composite material. The acid and alkali used in the kitchen will not corrode the quartz stone. If the acid or alkali sticks to the quartz stone, it can be effectively removed by washing it with water. Quartz stone has undergone more than 30 complicated polishing processes, and it will not cause harm to the quartz stone after long-term use. People do not need to waste manpower, material and financial resources to maintain the quartz stone.
The dense and non-porous design of the quartz stone leaves no place for bacteria to hide, even if the food is directly placed on the countertop, there will be no safety problems. The main material of quartz stone is silica, which does not contain any heavy metals that may cause radiation. 94% of quartz crystals and other resin additives make the quartz stone free of radiation pollution!
Quartz stone has been widely used in metallurgy, chemical industry, building materials, ceramics, and other industries. It is mainly used as raw material for manufacturing broken glass, sandpaper, and refractory materials and as an acidic solvent for melting iron. So do you know the physical and chemical properties of quartz stone?
The chemical composition of quartz stone is silicon dioxide, collectively called silica. It is a hard and extremely difficult to melt non-metallic mineral, usually containing more than 99.5%. There are 7 kinds of qualitative and identical variants of silicon dioxide, the pure and crystalline are called quartz, and the colorless and transparent hexagonal crystal is called crystal. Ordinary quartz generally refers to dense lumpy veined quartz. The color of quartz is generally white, gray, yellowish-brown, black, etc., with glass luster and translucent ore. It is brittle, without cleavage, and the fracture is shell-shaped. The hardness is 70 and the specific gravity is 2.65. Phosphorescence occurs during friction. It is chemically stable, insoluble in common acids, but soluble in hydrofluoric acid and concentrated alkali. It melts at a high temperature of 1710-1565°C, but does not volatility or decompose. After cooling, it becomes a transparent or translucent glassy substance called quartz glass. The grade and use of quartz stone are determined by the content of silica.
Quartz stone is stable, and it is difficult to affect its properties due to changes in the environment. Because of the high hardness of quartz, it is not easy to be scratched. Now the home decoration has played a good role.
