| Abstract: | The specific surface area of mercuric sulphide (a) has been determined by three methods: (a) gas adsorption method (N2 adsorption), (b) air permeability method and (c) microscopic method. The area values are compared. In the gas adsorption method, the effect of degassing temperature on the surface area of solid was studied. In the permeability method the porosity range over which the specific surface area remains constant was also determined. |
