Quartz Stone Grinding Powder Properties


Quartzite mainly refers to the widely distributed tripartite crystal system of low-temperature quartz (α-quartz). When the temperature is above 573 °C, it becomes a high-temperature quartz (β-quartz) of the hexagonal crystal system. Low-temperature quartz crystals are often hexagonal columns with pointed tops. There are horizontal stripes on the cylinder surface, and there is a difference between left-shaped crystals and right-shaped crystals. Dual crystals are common, commonly known as Dauphin dicrystalline and Brazilian dicrystalline.

(1) brittle;

(2) It has thermoelectricity;

(3) Refractive index 1.533 ~ 1.541, birefringence difference 0.009, dispersion 0.013;

(4) quartz has a strong piezoelectric property (Piezoelectric property), that is, when the force of the friction will produce sparks, which is the method of flint fire;

(5) Common inclusions in quartz are:

Haircrystal - mainly rutile;

Grass into crystal - mainly tourmaline;

Hydroblader crystals - liquid inclusions in quartz;

Blue quartz - contains light blue rutile needles;

Milk quartz - turbidity caused by fine water holes;

chlorite - composed of plate-like or fragmented chlorite, sometimes a green needle-like impotence;

Aventurine - The interior of the quartzite contains green or reddish-brown mica flakes, also known as flare quartz, commonly known as Tanglin stone.

Smoky black to dark brown smoky crystals are common, mainly because these rocks contain a larger amount of radioactive uranium and thorium.

Feature Benefits

Scratch no flower: quartz stone its quartz content is as high as 94%, quartz crystal is a natural mineral in nature with a hardness second only to diamonds, and its surface hardness can be as high as 7.5 on the Mohs scale, which is much larger than the sharp tools such as knives and shovels used in the kitchen, and will not be scratched by it.

Non-polluting: quartz stone is made under vacuum conditions, the surface of the same, dense and non-porous composite material, its quartz surface on the kitchen acid and alkali and other corrosion resistance, daily use of liquid substances will not penetrate its interior, long-term placed on the surface of the liquid only need to be wiped with water or clean and bright and other detergents with a rag can be erased, if necessary, the blade can be used to scrape off the surface of the retention.

Use is not old: the glossy surface of quartz stone is through more than 30 complex polishing treatment processes, will not be scratched by the blade, will not penetrate for liquid substances, will not produce yellowing and discoloration and other issues, daily cleaning only need to be rinsed with water, simple and easy. Even after a long period of use, the surface is as bright as the newly installed countertop, without maintenance and maintenance.

Can't burn: natural quartz crystals are typical refractory materials, its melting point is as high as 1300 degrees or more, 94% of the quartz stone made of natural quartz is completely flame retardant, will not be caused by contact with high temperature and cause combustion, but also has artificial stone and other table surfaces can not be compared with high temperature resistance characteristics.

Non-toxic and non-radiation: the surface of the quartz stone is smooth, flat and without scratch retention, and the dense and non-porous material structure makes the bacteria have nowhere to hide, and can be in direct contact with food, safe and non-toxic! Quartz stone using natural quartz crystalline minerals, its SiO2 content of more than 99.9%, and in the manufacturing process to remove impurities, raw materials do not contain any heavy metal impurities that may lead to radiation, 94% of quartz crystals and other resin additives make quartz stone no risk of radiation contamination.


There are many variations due to different particle sizes, colors, inclusions, etc.

(1) The crystals that show crystal are: colorless and transparent crystals; Purple amethyst (commonly known as amethyst); Smoky yellow, sooty brown to nearly black tea crystals, smoke crystals or ink crystals; Light yellow, transparent citrine; rose red rose quartz (commonly known as hibiscus stone); Milky white milky quartz. Spotted glittering aventurine due to the inclusion of scaly inclusions such as hematite or mica.

(2) Cryptocrystalline variants include: chalcedony (chalcedony) composed of fibrous microcrystallines; Agate of colloidal origin; Tiger's eye stone, etc., made of quartz with fibrous asbestos.

(3) Cryptocrystalline varieties are composed of granular microcrystals, often containing mixtures of other minerals, opaque, mainly flint, gray to black (commonly known as flint). Jasper, due to iron oxide impurities, is dark red or greenish yellow, turquoise and other colors. Large quartz crystals are mainly produced in pegmatite crystal caves; Lumpy often occurs in hydrothermal veins; Granular quartz is the main mineral component of many rocks such as granite, gneiss and sandstone. In addition to crystal, agate, etc. used as gemstones or craft materials, the purer general quartz is used as glass raw materials, abrasive materials, silicon refractory materials, etc. Impure quartz is a building material.

Main Uses

The main material of quartz stone is quartz, and the combination of rich colors gives it the texture of natural stone and a beautiful surface luster. Quartz stone countertops are colorful, Gobi series, crystal series, hemp stone series, shining star series are more distinctive, can be widely used in public buildings (hotels, restaurants, banks, hospitals, exhibitions, laboratories, etc.) and home decoration (kitchen countertops, face washstands, kitchen and bathroom walls, dining tables, coffee tables, window sills, door covers, etc.) field, is a non-radioactive pollution, reusable building interior decoration materials. It should be pointed out that the quality of quartz stone is directly related to the content of resin. The higher the content of quartz in quartz stone, the lower the amount of resin, the better the quality, the closer to natural, the less likely it is to deform. Experts pointed out that when the content of resin in quartz stone is greater than 10%, its corresponding technical indicators will decline.
