A STATISTICAL-ANALYSIS OF THE INFLUENCE OF PROCESSING CONDITIONS ON THE PROPERTIES OF FUSED-SILICA

In this work the quantitative relations between the properties of sint ered fused silica (density, mechanical propel-ties, cristobalite conte nt) and slip preparation parameters as well as sintering conditions (m illing balls material, temperature and rime of sintering) were establi shed Multifactorial experimental design ,cas used in ol der to obtain rite respective mathematical al models. The response surfaces of these models were analyzed, together with correlations between the compress ive and tensile strength and cristobalite content. it was established that the maximum values of mechanical properties for a given material were obtained with 6-8 vol.% of cristobalite in sintered samples.
