POROUS GRANULAR COMPACT

摘要

PURPOSE: To obtain ceramic fiber-contg. granular compacts usable as a porous granular filler having high porosity. CONSTITUTION: A mixture of 100 pts.wt. finely divided ceramic fibers having 50-150μm average fiber length with <=300 pts.wt. barium sulfate and 1-40 pts.wt. binder is granulated into granules having 0.1-5mm average diameter and 0.2-2.0g/cm<3> bulk density to obtain the objective granular compacts.
