The quartz powder is relatively coarse, below 325 mesh, the silica fume is relatively fine, more than 325 mesh. Whiteness, whiteness and hue are different because of impurities, and the purity is more than 99%. Microsilica, a by product of industry, is a mixture of sio2 and si. We are also called silica fume.
To a geologist or mineralogist, silica only means a SiO2 compound, regardless of its actual crystal structure. If you had pure SiO2 glass, you could describe it as being made of silica, and you can say that chemically, pure quartz is also SiO2. ...
Silica is an abundant mineral on the earth crust, and it is in sand, quartz and many other minerals. Some minerals have pure silica but, in some, silica are mixed with other elements. In Silica, the sulfur and oxygen atoms joined by covalent bonds to form a huge crystal structure.
Silica sand is a type of sand that contains granules of quartz. Quartz comes in a wide range of varieties ranging from different colours and microstructures. Silica sand is also composed of other fine particles like rocks and minerals. The difference between silica sand and washed sand is the latter is processed and the former isnt..

The size of the particles. Sand has larger pieces than powder . Silica and quartz are both common names for silicon dioxide.
Regular sand, also known as feldspathic sand, brown sand, or construction sand, will always contain some silica, but only in amounts less than 95%. For example, typical brown sand used for concrete applications can contain up to 80% SiO2, along with varying amounts of iron, carbonate, potassium, and other trace elements/minerals.
In this way, the quality of marble can be better. Therefore, the usage rate of quartz sand is quite high. , But many people still dont know much about quartz sand, so this article will help you popularize the difference between quartz sand and silica sand and the application of quartz sand in cement.
