High-grade silica sand is usually found as unconsolidated STORE below thin layers of soil and overburden. Subsequent quarrying, the sand regularly experiences impressive preparing before the deal. The handling may incorporate washing and cleaning of the grains, sizing to remove coarse and very fine fractions, and physical and chemical processes to remove impurities.

Multi Minerals Micro Silica is micronized high purity natural crystalline silica. It is inherently bright, white, low in moisture and chemically inert in nature. Due to its hardness, it yields improved durability and burnish resistance. Along with this, our Micronised Silica has excellent anti-foaming properties, sheen control with low resin consumption.

Fused silica is made of high purity crystal silica by electrically fusing (fusing temperature 1800-2000ºC) to amorphous Silicon dioxide , then they are classed to different grades by manual and then specially engineered to granular and powder form. Because fused silica has a very low thermal conductivity and excellent thermal shock resistance, it is used in lots of fields of investment casting,refractory,ceramic,epoxy modling compound,fusion bounded epoxy.
Chem&Size minerals is manufacturer/factory of Fused silica powder, fused silica flour, fused quartz powder, fused quart flour, which is made of fused silica ingot/lumps by Non-Iron ball mills technology.
Fused silica ingot/lumps is made of high purity crystal silica by electrically fusing (fusing temperature 1800-2000ºC) to amorphous Silicon dioxide, then it is classed to different grades by manual and then specially engineered to powder by ball mill.
Applications:
High volume stability, high purity but low volumetric expansion makes fused silica powder a very useful and versatile material for refractory applications or other highly cyclical applications.
Chem&size Minerals fused silica powder has a near zero thermal expansion coefficient, consistent chemistry and carefully controlled particle size distribution. Fused silica powder are designed for use in refractory, flow control/continuous casting, investment casting, precision casting, lost-wax process, technical thermal ceramic and other special applications. Fused silica powder has very high electrical resistivity and low thermal conductivity, so it used as filler in epoxy melding compounds for semi-conductors and fusion bounded epoxy powder coatings.
Applications Details Product:
To make crucibles that produce solar cells board in the photo-voltaic industry.
Fused silica powder is used to make rollers, constables, mortars, gunning mixtures and forming tools in the glass industry, make technical ceramic in the thermal resistance industry, to make ceramic slurry in investment and to make Acidic acid refractory, Fused silica precast shapes, Fused silica big blocks and fused silica constables.
Filler of epoxy melding compound
Filler of epoxy potting compound
Filler of silicon rubber
Filler of functional coating
Filler of fusion bonded epoxy powder coating.
Fused silica powder's Main Characteristic:
Lower linear expansion coefficient lower tension & lower radiation it is environmentally, no harm to workers and environment.
Vital To Life, We have played with it, admired it, and build houses with it. It has been a part of our diet since the beginning of time. One of the most abundant elements on the earth’s surface, Silica is present everywhere in our lives.
Silica is the most abundant mineral in the earth's crust, but you might not know much about it. We have established ourselves among the most prominent Manufacturers and Suppliers in the country. We manufacture extremely pure Silica
Silica is another name for the chemical compound silicon dioxide. Each unit of silica includes one atom of silicon and two atoms of oxygen. If you have never heard of silica before, you might be surprised to hear that you probably come into contact with it every day. Silica makes up the mineral called quartz, and it is the most abundant mineral in the earth's crust. It is the main component of most sand and the primary ingredient in glass. Every time you pick up a glass to take a drink, you are using silica.
Silica has been known to humans since ancient times, long before we knew it was made of silicon and oxygen. The art of making glass objects with silica dates back centuries. Today, there are many industrial uses for silica. These include abrasives, building materials, fillers, electronics, and water filtration. Our readiness to offer Silica as per clients’ demands has placed us among the superior Silica Suppliers and Silica Sand Exporters.
Properties:
The properties of silica include both chemical and physical properties such as hardness, color, melting and boiling point, and reactivity. Silica under normal conditions of temperature and pressure is a solid, crystallized mineral. It is relatively hard, rating a 7 on the Mohs scale, a scale used to measure the hardness of minerals relative to each other. The hardest mineral, diamond, rates 10 on the scale.
Pure silica is colorless, but if contaminants are present in a sample of quartz, it may be colored. For instance, rose quartz is silica with trace amounts of iron. This gives it a pinkish hue. Milky quartz is simply silica with air bubbles or inclusions of liquid that make the mineral appear white.
its used in glass manufacturing ,silicate manufacturing and tiles manufacturing ,product having 98% sio2 ,and 2% other impurity
also available in size (16 mesh to 24 mesh)
