EFFECTS OF AGGREGATE CONTENT ON THE INTERCONNECTED PORE FORMATION AND PROPERTIES OF POROUS PURGING PLUG MATERIALS

The physical properties and microstructure of porous purging plug materials with different aggregate contents and prepared at different firing temperatures were investigated by means of X-ray diffraction, scanning electron microscopy, air permeability, pore size distribution, apparent porosity, bulk...
