Interionic potentials in ionic solids, wood price has increased three fold during the last five years. The forest area per capita(hactare) and the fuel wood consumption per capita (Kg of coal equivalent) for some of the developing countries is shown[1] in fig.1.1. It is seen from this figure that in many countries there is a shortage of
