give me the details about crystals what is purpose about industrial use?

Gemstone quality crystals can be made into jewellery and so are vauable. Others are useful for their ores (hematite Fe2O3 iron ore, malachite copper ore etc.) I also heard somehing about using crystals for resonance but I'm not sure what that means lol hope this helps\n\nP.S. Quartz ie. silicon used for glass

Theoretically one can grow as big monocryistals as he have material...\nBut I am not sure that it is possible in practice...\n\nand besides, it would cost too much, and today, no one really needs such a big Crystal (they use big ones in lasers, but not 30ft. ones).\n\nyou can have some molecular physics book to see the technology, which is based on a principle, that in certain circumstances the atoms of Crystal get oriented, and if you have those circumstances (temperature, humidity, pressure etc.) you will have  a monocrystals

I'm not familiar with this material, but sometimes websites that give info on materials and compounds include IR-specs.  Or, if you have a sample, call your local university.  Some one may be able to help you there.

you can use any part of the elecromagnetic spectrum for for solar power as long as the material can absorb it and produce electricity. \n\na crystal radio ( or even a regular radio ) uses the radio waves ( not visible ) to create a tiny current in the radio that are converted to sound waves for our pleasure.  \n\nwhat part of the spectrum used depends entirely on your choice of material.

If you are looking for properties of some specific chemical then search for MSDS (Material Safety Dada Sheet) for that particular chemical in Google or Yahoo search engines.\nHere, I am giving you a list of websites which can give you general information on symbols. There will be slight variation in the depth of descriptive material depending on site to site.\nYou can copy and paste following links in your browser's address line:\n(1) www.geocities.com/david_charles_curran/safety\n(2) http://en.wikipedia.org/wiki/Hazard_symbol\n(3) http://www.hse.gov.uk/chip/phrases.htm\n(4) http://www.chem.utoronto.ca/healthsafety/guide/symbols.htm

Not  necessary. When the thickness is high ordinary ray of light is absorbed by the crystal and only the extra-ordinary light comes out.\n\nIf  cut we can  identify the position of crystal to produce the polaraised light.

Crystal "defects" can be due to imputities. This is common with diamonds.

a crystal structure is a unique arrangement of atoms in a crystal. A crystal structure is composed of a unit cell, a set of atoms arranged in a particular way; which is periodically repeated in three dimensions on a lattice. The spacing between unit cells in various directions is called its lattice parameters. The symmetry properties of the crystal are embodied in its space group. A crystal's structure and symmetry play a role in determining many of its properties, such as cleavage, electronic band structure, and optical properties.\n\n\nThe crystal structure of a material is often discussed in terms of its unit cell. The unit cell is a spatial arrangement of atoms which is tiled in three-dimensional space to describe the crystal. The unit cell is given by its lattice parameters, the length of the cell edges and the angles between them, while the positions of the atoms inside the unit cell are described by the set of atomic positions (xi,yi,zi) measured from a lattice point.\n\nFor each crystal structure there is a conventional unit cell, which is the smallest unit that has the full symmetry of the crystal (see below). However, the conventional unit cell is not always the smallest possible choice. A primitive unit cell of a particular crystal structure is the smallest possible unit cell one can construct such that, when tiled, it completely fills space. This primitive unit cell does not, however, display all the symmetries inherent in the crystal. A Wigner-Seitz cell is a particular kind of primitive cell which has the same symmetry as the lattice.\n\n\nfor further clarifications go to the site listed

There are several uses for this.  Generally for chemistry students the effort teaches them how the measurements are made, good laboratory techniques, and hopefully, some insight into chemistry and the physical sciences.  It doesn't always work, but it makes a good experiment. \n\nFor those who are in the business of using various substances, it is very important to know what their physical properties are, and how they relate to the physical properties of other substances.  Your air conditioner was designed around those measurements, as was your car, paint, furnace, and just about everything that was manufactured around you.  \n\nWhile nature obviously doesn't carefully record properties in a lab book, they are important to how plants and animals work, how hard rocks are, how ice forms, etc.  Without understanding these properties, we can't understand nature or ourselves completely.

An ore has minerals or metals suspended in a base, unwanted material that needs to be refined to make the pure mineral or metal usable.\n\nA gem is a crystaline material that has some intrinsic value.

A crystal is non-living, does it make any sense for it to grow, as they do, 'knowing' what color to be, what shape and size and how many facets and what angles to have and what clarity and hardness to have and what refractive index to have and give off little baby crystals which will grow up in the likeness of the parent. You could liken our DNA to a kind of protein crystal, It 'knows' what to do because the data is contained within its molecular structure. There is no reason for it so it makes no sense but none the less, it occurs naturally. We have to accept that we were created by our genes as a mere vehicle for its own use.

The manufactures take a couple of lasers (2-3), each laser not having enough heat/energy to melt the crystal. Then they cause the lasers to intersect at each point that they want one of those little bubbles to appear and where the lasers intersect they add their energy together and melts the crystal. the placement of each dot is controlled by a 3-d graphics design inside of a computer.

It depends on which method you are talking about and the end use of the water.  For drinking water they are strictly monitored.  For industrial reuse, you try to balance cost and quality so you can have problems.
