 note = {To determine the effect of composition and heat-treatment of mother grass on pore structure and rate process of acid treatment, a nitrogen adsorption experiment was run and measurements of the porous layer thickness were taken. In the case where the mother grass did not contain any alumina, pore size broadened with heat-treatment time. On the other hand, when it contained a small amount alumina and heat-treated at a suitable temperature of 550°C, the pore structure was little affected by heat-treatment. Surface area was controlled in the range of 100 to 400 m^2/g by the Na_2O/B_2O_3 ratio. The mean pore radius was 43Å and was largest at a Na_2O/B_2O_3 ratio of 0.172. The effective diffusion coefficient was increased with pore size. Dissolution constant was not related to the Na_2O/B_2O_3 ratio, but it increased with pore volume.},
