Cast-iron is either pure iron or some alloy of it melted until it's liquefied, then cast in a mold. It's relatively brittle, but because of its low melting point and easy casting, it's widely used for pipes, machines, and parts of cars, as they can be easily produced with these molds.
Minerals are classified by chemical formula, composition, physical properties, optical properties, and special properties. The Dana Classification System is a chemical classification for minerals, and the Strunz Classification System (chemical-structural) are two systems designed for mineral classification.
yes its dependent on the microstructures of the composites. my friend told me about " TAIZHOU DOUBLE WORLD PLASTIC & MOULD CO., LTD ". who Manufacturer PET bottles. i am going to contact my friend and told him about this.

Properties of materials depends on the chemical composition.
Several chemical properties can be estimated knowing the chemical composition.

Chemistry is the scientific study of the composition structure and properties of matter and the changes that it undergoes.
Each mineral has a unique composition and definite set of properties. Often an alternate may be found for some of these properties. For example there are many piezoelectric materials that will substitute for quartz in some applications.
Chemistry is the scientific study of the composition structure and properties of matter and the changes that it undergoes.
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
