properties of materials in making jewelryjewelry

Classification of Magnetic Materials - On the basis of their magnetic properties different materials are classified as: Diamagnetic substance Paramagnetic substance Ferromagnetic substan..

Matter and Materials - Matter exists in several phases. If we look at all objects around us, we perceive that some materials have a definite shape and occupy a definite amount of space or volume. We call these materials solids and we can name many objects that are soli..

(e.g., TiO 2 , NaCl, C 6 H 6 ) are weakly repelled by external magnetic fields. This property is shown only by those substances which contain fully-filled orbitals i.e., no unpaired electrons is presen..

Polyethylene has a low softening point of 383K and a low specific gravity of 0.22. The material is tough flexible highly insulating water resistin..

As we have seen, glass is a mixture of number of silicates. Therefore, when heated, it does not melt at a fixed temperature. But, it softens gradually and hence can be moulded into any desired shape. It is this property that makes glass one of the widely used materials..

Properties of Steel - The properties of steel depend on the carbon content and the heat treatment imparted to it. If the carbon content is low, the steel is soft and ductile and is called mild steel. As the carbon content increases, the ductility decreases, but the tensile stren..

The properties of steel depend on the carbon content and the heat treatment imparted to it. If the carbon content is low, the steel is soft and ductile and is called mild steel. As the carbon content increases, the ductility decreases, but the tensile strength increase upto 1.5% of carbon..

Neoprene is superior to natural rubber because of the following properties: Neoprene is non-inflammable but natural rubber is inflammable. Neoprene is resistant to oils, organic solvents, petrol and grease. Natural rubber swells and rots in contact with these materials. ..

Hydrogen is a colourless, odourless and tasteless gas. Impure hydrogen has a fishy smell due to its impurities ,arsine and phosphine. Hydrogen is the lightest element. It is by far the most abundant element in the universe and makes up about 90% of the universe by weight. Hydrogen as..
