• Description:
  A computer program is set up in Fortran language to calculate pore size distribution using the Cranston-Inkley method of calculation. Nitrogen (7727379) adsorption isotherms are determined on amosite and chrysotile asbestos at minus 195 degrees-C. Size reduction is found to have a major effect on increasing pore volumes of both asbestos (1332214) materials. Bar graphs are given showing the effect of grinding on the pore size distribution of amosite and chrysotile (12001295) and the effect of preconditioning temperature on the pore size distribution of mechanically dispersed amosite and chrysotile. Though chrysotile is much more porous than amosite, similarly processed samples of amosite and chrysotile have similar average pore diameters. [Description provided by NIOSH]
