Ab&aet

-Measurement of the density of fine powders by pycnometry IS subject to error especially when the particles are porous Pycnometnc hquld may enter the particle pores to an unknown extent or may not enter all mterstltml space The appllcatlon of pressure may crush porous particles altenng their ongmal densrty In ttus paper the dtierent effects are exammed analflcally and equations and graphs are presented to show the extent of potential error Expertmental results are reported which show that with particle size less than about 100 pm mercury pycnometry can gve rmsleadmg results because of mcomplete mterstltlal penetration
