High density fused silica mixes refractory shapes made

As a consequence it has been necessary to utilize slip casting to make fused silica shapes having densities from 117 to 122 pcf Such density and also high strengths are required since such shapes are used in areas such a chlorinators and other appliion where low porosity low permeability and acid resistance are of paramount importance

321 Porosity from Laboratory Measurements PNG 301

A second method the Resaturation Method uses a clean dry core sample and resaturates it with a fluid of known densityThe change in weight of the sample can then be used to determine the pore volume V p of the sample Since the fluid can only enter or leave the connected pores the porosity obtained from the resaturation method is the effective porosity ϕ e
