Difference Between Silica and Silicon Dioxide

Aug 20, 2018The key difference between silica and silicon dioxide is that the silica is the common name of SiO 2 whereas silicon dioxide is the IUPAC name of SiO 2. Moreover, silicon dioxide refers to the purest form only while silica can be either pure or impure form. Both terms "silica" and "silicon dioxide" refers to the same chemical compound, but they are different in the usage of these terms.

Compare swimming pool filters: sand vs glass vs OC

Apr 07, 2017Sand: Sand is the benchmark for glass and OC-1 comparisons. Sand filter media offers no energy or water savings. Weekly backwashing is required in sand filters to reduce built-up in pressure as a result of debris settling in the sand bed. This uses a substantial amount of water. This water is then replaced and re-heated. Both at a cost.

Abrasive blasting

Mineral: Silica sand can be used as a type of mineral abrasive. It tends to break up quickly, creating large quantities of dust, exposing the operator to the potential development of silicosis, a debilitating lung disease. To counter this hazard, silica sand for blasting is often coated with resins to control the dust.
