9. CsCI is ionically bonded with radius= 0.94 and CN= 8. eight chloride ion surround a central cation at the (½,½,½) position CsBr,TICI and TIBr have similar structure

10. Hardness- Very High Elastic modulus- Very High Thermal expansion- High Ductility- Low Corrosion resistance- High Wear resistance- High Electrical conductivity- Depends on material Density- Low Thermal conductivity- Depends on material Magnetic- Depends on material

11. Ceramic tile is a beautiful, tough and enduring floor and wall covering material. Apart from its very presentable look, it is resistant to almost all of the common sources of wear endured by quality flooring.

13. Thermal shock resistance A properly laid ceramic tile floor will neither deform nor break in extreme temperature conditions. Chemical resistance Ceramic tile materials are highly resistant to chemical agents. Color permanence Direct exposure of ceramic tiles to sunlight neither alters their color, nor causes them to fade. Hygiene Being hygienic and easy to clean, ceramic tiles are recommended for all areas where high sanitary standards are a must.

14. One of the first limitation of ceramic braces is that they are fragile. Ceramic is a naturally brittle material, so the braces will be more fragile than those made with metal. Ceramic braces will easily chip or break if you're not careful. When they break, the sharp edges may even cut your lip. Another limitation of ceramic braces is that they may wear your teeth down. Ceramic is harder than the enamel on your teeth. If the brackets are put on your lower teeth, your upper teeth will be worn down because because they are in constant contact with the ceramic brackets.

15. Removal is also limitation of ceramic braces. They are known for being very difficult to remove. In some cases, removal can be painful to the patient. Ceramic braces may also damage one of your teeth upon removal if they break and leave a piece stuck to one of your teeth. Ceramic braces are also easily stained. If they become stained, then they will lose their tooth-like color and become more visible to other people. If you have ceramic braces, you will have to pay more attention to the foods you eat and to your oral hygiene. Last limitation of ceramic braces is the length of time it takes for correction. It normally takes a longer time for these braces to correct your teeth than it would for metal braces. This is due to the fact that your teeth will move slower because the ceramic surface experiences more friction between the wire.

16. Size does make a difference! For many years the general advice from designers was that small bathrooms required the use of small tile! Actually that advice has been made obsolete in the last ten years with the availability of large body tiles. As the tiles increase in size, the amount of grout lines is reduced and the floors are not only then easier to take care of but make the room look bigger as they are less busy

17. The backsplash is the focal point of the kitchen and bath and often sets the tone for the rest of the house. The best advice is that you should not install the backsplash, in fact you should not even think about selecting your backsplash tile, until your countertops, cabinets and other decorating plans are set and finished. It is very difficult to carry color, texture, size and design in your mind’s eye while trying to imagine what your countertop and or cabinets will look like after they have been installed! It is so much easier to take the samples and put them in the shadows of your cabinets and allow the reflection of your new countertops to affect the tile color so that you can make the proper selection.
