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

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. This product gets easily mixed and can be used for high temperature applications like flat glass, furnace tubes and many more due to its excellent thermal expansion, hardness. It yields improved durability and burnish resistance.
