aluminiu:Aluminium is a silvery-white, lightweight metal. It is soft and malleable. Aluminium is used in a huge variety of products including cans, foils, kitchen utensils, window frames, beer kegs and aeroplane parts. This is because of its particular properties.
mica : der and also helps to brighten the tone of coloured pigments. It is a superior insulator. So in the electrical industry it is used as thermal insulation, and in electronic equipment as electrical insulators.
limestone : quicklime (calcium oxide), slaked lime (calcium hydroxide), cement and mortar. Pulverized limestone is used as a soil conditioner to neutralize acidic soils (agricultural lime). Is crushed for use as aggregate—the solid base for many roads as well as in asphalt concrete.
