Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Silicate shopping experience:
1. Compare - without doubt the biggest advantage that the Silicate offers shoppers today is the ability to compare thousands of Silicate at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.
2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about
3. Testimonials - don't know anybody that has bought a Silicate? Wrong! If the Silicate is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.
4. Questions - Got a question about Silicate then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....
5. Reputation - Never heard of the company selling Silicate? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Silicate and build up a picture of their reputation for sales, returns, customer service, delivery etc.
6. Returns - still worried that even after all of the above your Silicate wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.
7. Feedback - happy with your Silicate then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.
8. Security - check for the yellow padlock on the Silicate site before you buy, and the s after http:/ /i.e. https:// = a secure site
9. Contact - got a question about Silicate, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.
10. Payment - ready to pay for your Silicate, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.

In chemistry, a
silicate is a compound containing an anion in which one or more central silicon atoms are surrounded by electronegative ligands. This definition is broad enough to include species such as hexafluorosilicate ("fluorosilicate"), 2−, but the silicate species that are encountered most often consist of silicon with
oxygen as the ligand. Silicate anions, with a negative net electrical charge, must have that charge balanced by other cations to make an electrically neutral compound.
Silica, or silicon dioxide, SiO2, is sometimes considered a silicate, although it is the special case with no negative charge and no need for counter-ions. Silica is found in nature as the
mineral quartz, and its polymorphism (materials science).
In the vast majority of silicates, including
silicate minerals, the Si atom shows
tetrahedron coordination by 4 oxygens. In different
minerals the tetrahedra show different degrees of
polymer: they occur singly, joined together in pairs, in larger finite clusters including rings, in chains, double chains, sheets, and three-dimensional frameworks. The minerals are classified into groups based on these anion structures; a list is given below.
Silicon may adopt
octahedron coordination by 6 oxygens at very high pressure, as in the dense
stishovite polymorph of silica that is found in the lower mantle of the Earth, and which is also formed by shock during
meteorite impacts. Lack of space around the oxygen atoms makes this coordination for Si very rare at normal pressure, but it is known in the hexahydroxysilicate anion, 2−, as found in the mineral
thaumasite.
Silicate rock
In
geology and
astronomy, the term
silicate is used to denote types of
Rock (geology) that consist predominantly of
silicate minerals. Such rocks include a wide range of
igneous, Metamorphic rock and
sedimentary types. Most of the Earth's mantle and crust (geology) are made up of silicate rocks. The same is true of the
Moon and the other rocky planets.
On Earth, a wide variety of silicate minerals occur in an even wider range of combinations as a result of the processes that form and re-work the crust. These processes include partial melting, crystallization, fractionation, metamorphism, weathering and diagenesis. Living things also contribute to the silicate cycle near the Earth's surface. A type of
plankton known as diatoms construct their
exoskeletons, known as tests, from silica. The tests of dead diatoms are a major constituent of deep ocean
sedimentSilicates have been observed in space, around evolved stars and planetary nebulae such as
NGC 6302. They are found in both amorphous form and crystalline form, though the range of types that have been found is far smaller than those found on Earth.
Mineralogy
Mineralogy, silicate minerals are divided according to structure of their silicate anion into the following groups:
- Silicate_minerals#Nesosilicates_or_Isosilicatess (lone tetrahedron) - 4−, eg olivine.
- Sorosilicates (double tetrahedra) - 6−, eg epidote.
- Cyclosilicates (rings) - 2n−, eg tourmaline group.
- Inosilicates (single chain) - 2n−, eg pyroxene group.
- Inosilicates(double chain) - 6n−, eg amphibole group.
- Phyllosilicates (sheets) - 2n−, eg micas and clays.
- Tectosilicates (3D framework) - x−, eg quartz, feldspars, zeolites.
Note that tectosilicates can only have additional cations if some of the silicon is replaced by a lower-charge cation such as aluminium, to give a negative charge overall. This substitution can also take place in other types of silicate.
Some rare minerals have more than one type of anion coexisting in their crystal structures, or complex-shaped anions that are intermediate between the simple types above.
