What are the raw materials necessary for melamine production?
These are the requirements
of the high pressure (no catalyst) Eurotecnica
process.
They are: 1) Ammonia2) Carbon dioxide
These form Ammonium Carbamate
and then it decomposes to form Urea and Water. The Urea then decomposes to Cyanic
Acid and Ammonia. The Cyanic
Acid finally polymerizes to give Melamine.

Which raw material contains nitrogen?
The most abundant natural sources of nitrogen are nitrates, which are generally the result of long years of accumulation of guano (from bird nesting sites - seriously, it used to be very valuable business) although there are also some geological deposits (which I guess could simply be fossil guano).The modern most common raw material for nitrogen is urea, which is also created by animals (in urine) but is much more important because it can be manufactured. It is chemically related to ammonia, which can also be manufactured and in some cases is used to make urea, but urea is the more common raw material since it is easier to handle, store, and transport than ammonia. The discovery of practical ways to manufacture ammonia and urea in large quantity was due to Bosch in Germany around the time of the first world war. It revolutionized war and farming, because explosives and fertilizer could be made from coal energy instead of needing to dig up bird guano from the coasts of Peru or Chile and ship it half way around the world.Read more: Which_raw_material_contains_nitrogen
Why did the British want Indians to export raw materials?
The British wanted the Indians to export raw materials to Britain as Indian raw materials were of good quality, low cost and also as the Indian market would accept the goods whose raw materials originated there. Another reason is that the British knew that once trade was successfully established, it would be easier to colonize Indian Princely States.

What is non material and material culture?
Material culture is the physical or technological aspects of a culture in our daily lives. In laymen's terms, things that show our social class, and how we live, materially. "Do we place a lot of emphasis on our material possessions or not?" Examples of this would be our cars, houses, clothing, computers (or other technological gadgets) etc.Non-material culture is the cultural adjustments to material conditions, or in laymen's terms our customs, beliefs, patterns of communication, and the ways we use material objects. Examples of this include, politics, economics, language, rules, customs, family, religion or beliefs, values, and knowledge.
