Silica sand also known as quartz sand white sand or industrial sand is made up of two main elements silica and oxygen Specifically silica sand is made up of silicon dioxide (SiO2) The most common form of SiO2 is quartz – a chemically inert and relatively hard mineral SiO2 grades at a 7 out of 10 on Mohs hardness scale making it.Silica sand has for a long time been used to clean as well as purify the water 4 grades of silica sand are majorly used for water filtration all over the world Earliest recorded of the silica sand has been traced back to the year 1804 when a man by the name John Gibb was able to design as well as install an experimental filters.Read More
May 20 2020 Sources of Silica Sand SiO2 is the chemical sign of silica and it is actually the group of minerals which is a mixture of Oxygen and Silicon This sand is often got in the crystalline state and because of weathering plankton fossilization takes place and that results in crystallizing SiO2 In most regions of the world these are found as mines and it is obtained in high hardness.Silica Sand is actually a granular material It contains quartz and minute amounts of coal clay Sometimes it has minerals in it People call it quartz sand too Most importantly it is the industrial sand Quartz over time turns into Silica sand gradually because of the influence of water and wind.Read More
