Terms in this set (43)
Elements from the central region of the Periodic Table-they are hard,strong,dense metals that form compounds that are often colored.
Mixture of elements(usually metals) designed to have the properties useful for a particular purpose.
A furnace for smelting iron ores such as hematite (Fe2O3) with carbon to produce pig (or cast) iron (in modified form the furnace can be used to extract metals such as zinc).
A process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction.
A hard, strong grey or bluish-grey alloy of iron with carbon and usually other elements.
The product formed when buring steel combines with oxygen.
Basic oxygen process
The process used to make still from iron from the blast furnace: oxygen is blown into molten iron using an 'oxygen lace' and lime is added to remove non-metallic impurities.
Alloys of iron and carbon only; the amount of carbon in steels can vary between 0.2% and 1.5%.
A steel that is alloyed with a variety of elements.
A loose, orange-brown,flaky layer of hydrated iron(III)oxide,Fe2O3.xH2O,found on the surface of iron or steel.
The electrolysis of aluminium in an acidic solution.
Process of coating a surface in order to improve aesthetics and protect from environmental factors.
Process of coating a surface of a substance with oil.
Process of coating a surface of a substance with plastic.
A process of electrolysis in which a metal object is coated(plated)with a layer of another metal.
The protection of iron and steel objects by coating with a layer of zinc.
Attaching iron to a more reactive metal.
A technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell.
Ore from which aluminum is made.
The direct use of atmospheric nitrogen in the formation of important compounds of nitrogen.
A chemical or natural substance added to soil or land to increase its fertility.
Compound fertilizers are classified as either two-element (phosphorus-potassium, nitrogen-phosphorus, and nitrogen-potassium) or three-element (nitrogen-phosphorus-potassium).
Straight N fertilizers
·Straight fertilizer usually contributes one of these 3 main nutrients to the crops which are Nitrogen (N), Phosphorus (P) and Potassium (K) or mostly known as NPK.
NPK compound fertilizers
A range of compound fertilizers with a combination of nitrogen, phosphorus and potassium (NPK).
Inorganic fertilizers, also referred to as synthetic fertilizers, are manufactured artificially and contain minerals or synthetic chemicals.
A chemical element with symbol N and atomic number 7.
Phosphorus is a chemical element with symbol P and atomic number 15. Because it is highly reactive, phosphorus is never found as a free element on Earth.
Potassium is a chemical element with symbol K and atomic number 19.
A dense, corrosive liquid consisting of concentrated sulphuric acid containing excess sulphur trioxide in solution.
A serious reduction in the body's water content
Water saturated with salt.
Mercury cathode cell
in this, sodium(Na) is produced at, and dissolves in the flowing mercury (Hg) cathode. sodium hydroxide is produced by treating the Na-Hg cathode material with water.
Here the products of electrolysis are kept separate by an asbestad diaphragm.
This is the most modern system and it uses a selective ion- exchange membrane to keep the products apart.
Element in group VII of the periodic table - generally the mossy reactive group of non metals.
Made by heating powdered limestone with clay in a rotary kiln.
A mixture of cement and aggregate/crushed rock(stone chipping and gravel). Then it is mixed with water and can be poured into wooden moulds.
Acidic or poisonous gas are released into the atmosphere
Liquid waste and cooling water from chemical plants are released into the river.
Solid waste that are poisonous are dumped on the ground.
Appearance of the surroundings
Quarrying and mining can leave the land surrounding a chemical plant looking very much the worse for wear.
Ammonium nitrate is one of it types of fertilizer.
also known as lubricant, they are introduced between two moving surfaces to reduce the friction between them.
