How do you separate iron III oxide and silicon dioxide?
You should be able to use a magnet to attract the iron out of the sand (silicon dioxide)
What raw materials does Starbucks use?
Coffee is a natural ingredient taken from coffee beans.
Why is silicon dioxide use to make bricks?
Bricks are usually made from clays, whch contain silicates. Silicon dioxide may be present in the mixture.
What is use of silicon dioxide in integrate circuit?
for the insulation purpose.
Use of silicon?
Silicon is used to make many electronic devices,such as transistors, integrated circuits and computer chips.
How much money is silicon dioxide?
This depends on the quality, use, form, quantity.
Carbon dioxide is used by plants for what?
It is used in photosynthesis, which turns sunlight, carbon-dioxide, and water into food the cell can use. Go to Wikipedia and search photosynthesis for more information.
Is titanium dioxide use for bath soap?
Titanium dioxide is sometimes used for bath soap. It is not however an active ingredient, it is merely a reagent used to give the soap a more white appearance.
What properties of silicon dioxide make it sueful in sandpaper?
Use/equipment Your chemical dioxide Main properties to use Chemical or physical properties? Fire extinguisher Carbon dioxide - CO2 does not conduct electricity. - CO2 is heavy (dense) so it covers fire and removes the oxygen. - CO2 does not burn. Physical physical chemical Electrical wires Copper -copper can bend (malleable) -conducts electricity - does not corrode easily Physical Physical Chemical Welding Argon -very unreactive, so it provides an inert atmosphere. Chemical Sand paper Silicon dioxide It very hard and does not crumble (not brittle) -High melting point Physical Physical Tools Iron -Iron is strong and hard -Iron can change shape (malleable) Physical Physical Computer circuits Silicon -Silicon can conduct electricity. -silicon has very high melting points.

Is silicon toxic?
According to wikipedia: "Pure silicon dioxide produces no fumes and is insoluble in vivo. It is indigestible, with zero nutritional value and zero toxicity. When silica is ingested orally, it passes unchanged through the gastrointestinal tract, exiting in the feces, leaving no trace behind." Inhalation of small quantities over time however can lead to silicosis and bronchitis. http://en.wikipedia.org/wiki/SilicaToxicity fears may be due to the the fact that asbestos is a silicate containing a combination of silicon and oxygen similar to that found in silicon dioxide (sand) but with long, thin fibrous crystals.Update:"...it is naturally 'low in toxicity'...a theory that silicon dioxide may cause Chronic Fatigue Syndrome. The symptoms Fraser experienced from supplements that contained silicon dioxide were similar to those experienced by women when their breast implants leak, which contain a significant amount of silicon dioxide..."http://www.ehow.com/about_5108396_use-silicon-dioxide-fat-burners.HTMLlow in toxicity? low over and over again equals high. just like the drinking water, other preservatives, the air, everything. u add up 5 cents enough it will equal a million dollars. i wouldn't use it.
What are the uses of silicon oxide in a mobile phone?
As in all modern electronic devices, a microscopically thin layer of silicon dioxide is grown as an insulator and passivator over the silicon of integrated circuits and discrete transistors. This process was developed in 1959 by Fairchild Semiconductor for use in their Planar Process for making silicon transistors and immediately spread throughout the industry, permitting use of inexpensive plastic packaging for semiconductor devices for the first time. Silicon oxide polymers are also in the silicone rubber parts that seal the case and keyboard from moisture.
Is it safe to use super glue on silicon?
It's best to use silicone on silicon.
