1) Introduction: if you think about the development of hmman civilization, you will find that the pace of social and economic growth has been closely releated to the proficiency with which the people have bee able to use the material and chemical inthe world around them.
in the beginning this was through keen observation and trial and error. thousands of years ago, men and women discovered perhaps by accident, that they could hunt more easily if they could sharpened rocks into wepons. they discovered that certian herbs helped to heal the wounds. once they discovered these properties of the materials arround them, they remaembered these and started using them.
2)the magic of new materials: there are somany new materisls avalible nowadays which our grandparents did not have access to. our houses are full of mordern materials:stainless stell, fiber glass, plastics, musical and audio-visual materials. in the world ut side there are somany new materialas well: light-weight, high performence, alloys help us to built aircraft, satellites, launch vegicles and missiles and various kinds of plastics.
3) Is it necessary to have material resourses inorder to be a developed country?:
many developed countries possess rich materials the US( copper, gold, lead, lithium,molybdenum,rare earths,zinc among others), Russia( Gold, Iron ore, Lead, and Nickel), China( gold, oil, iron ore, molybdenum, and rare earths,) and Austrilia(coal, iron, oil, bauxite,copper,gold,lead and nickel) are all examples of this. however the presence of material resources doesnot ensure that a country can become developed. but the usage and the hard work of bringing them to lime light can develop the country.
g a wide range of essential .
a) iron: about 98% of iron ore is use to make steel, one most useful materials ever created. while the other uses for iron ore and iron account for only a very small amount of the consumption, they are wide rangeing and include magnets, car parts, medicines, printing inks, plastics and fertilizers.
b) manganese ore: steel becomes harder when it is alloyed with manganese therefor the most important use of the material is in the manfacture of steel.
c) titanium: is a strong , light weightmetal often used in the aeroplains and in several applications as a subistute for steel.
d) Aluminium: bauxite is the main sourse of aluminium. the lightness, strength and corrission resistance of aluminium are important consideration in its applications.
e) berylores: beryllium is very ligh and has a high melting point its alloys are used mostly for aerospace products, automobilies, computers,oil, and gas drillind equipment and telecumminication.
f) coal: an all- important sourse of energy which india has in plenty.
indias mineing program does not refelect the diversity of minerals avalible in the country.
coal is called the black gold and largest of its mines are found in Andrapradesh, orrissa, and bihar.
hence its important for the economical development.
5) the steel industry in india: steel, an alloy of iron and carbon , can be produced in many forms. at the lowest end of the range of iron products is pig iron, which is used in the steel making process. hence it is very important running aterial for the economic development.
6)conclusion:material and the manafacturing are core of mordern human civilizatio. over the year like civilization itself, manfacturing as evolved, absorbed new chnologies and created new cutting-edge products.
hence the material and the future is very important for the development in the comming days.
