INTRODUCTION

Introduction

Aluminium because of its low density, high tensile strength and resistance to corrosion is widely used for the manufacture of aeroplanes, automobiles lawn furniture as well as for aluminium cans. Being good conductor of electricity it is used for transmission of electricity. Aluminium is also used for making utensils. The recycling of aluminium cans and other aluminium products is a very positive contribution to saving our natural resources. Most of the recycled aluminium is melted and recast into other aluminium metal products or used in the production of various aluminium compounds, the most common of which are the alums. Alums are double sulphates having general formula

X2SO4.M2(SO4)3.24H2O

X = Monovalent cation;            M = Trivalent cation

Some important alum and their names are given below:

K2SO4.Al2(SO4)3.24H2O – Potash Alum

Na2SO4.Al2(SO4)3.24H2O - Soda Alum

Introduction

K2SO4.Cr2(SO4)3.24H2O – Chrome Alum
