اقرأ أكثرIn 2014, Flook put forward a new quality index according to the needs of the market industry. It believed that quartz with a purity of SiO2 of 99.95% and a total impurity content of less than 5/10,000 was high-purity quartz, and quartz with a purity of 99.5%~99.8% could meet the requirements of semiconductors.
اقرأ أكثرSilica is another name for Silicon dioxide, SiO2, of which quartz is a specific latticed structure. So silica sand is quartz that over the years, through the work of water and wind, has been broken down into tiny granules. These granules can be used for many different purposes, and can be found in most non-tropical regions of the world.

اقرأ أكثرThe chemical composition of quartz is silicon dioxide (SiO2), and high-purity quartz sand means that the SiO2 content is higher than 99.9%. Quartz sand is a silicate raw material obtained through crushing and purification. To make high-purity and ultra-high-purity quartz raw materials, it is necessary to remove all impurities except silica.
اقرأ أكثرSilica 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 ...
