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.

Fused silica Introduction  Fused silica is made of high purity crystal silica by electrically fusing (fusing temperature 1800-2000â??) to amorphous Silicon dioxide , then it was 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. Fused Silica Properties   Investment Casting Grade 2.1 SiO2 >99.90% 2.2 Al2O3

As a general rule, The purer the sand, the clearer the products Silicon and oxygen are the earth's two most abundant elements and together they make silica, one of the earths three most common rock forming minerals. Akshar Minerals Silica sand is high purity natural crystalline silica. It is inherently bright, white, low in moisture and chemically inert in nature. Basically, It is made up of two main element Silica & Oxygen. Silica sand is made up of Silicon Dioxide. There are number of different uses of silica sand in the industrial and commercial sector, from golf courses to glass making . The chemical formula of Silica Sand is SiO2 Characteristics : High Purity Weather Resistant White Appearance Naturally Hard Controlled Particle size Chemically Inert Applications Akshar Minerals Silica sand is used depends on physical, chemical and mechanical characteristics such as grain size, shape color, structure and distribution as well as refractoriness strength and stability. There characteristics can differ depending on how mineral is processed after it is mined.
