"Discriminating Opaline Phases from Cristobalite and Tridymite in Clays"
Abstract: This talk centers on continued characterizations and evaluations to discriminate an opaline phase from that of regulated cristobalite and tridymite phases and when these opaline phases are within clay matrices. Present regulations consider crystalline silica (quartz, cristobalite, tridymite) as “known human carcinogen”. Opal-A, a silica hydrate, has a radial distribution pattern resembling the X-ray diffraction pattern of cristsobalite where analysts and regulators misinterpret opal-A as cristobalite. Additional misinterpretations arise with the opaline states, opal-CT and opal-C. Historically, Jones and Signet proposed that opal-CT and opal-C had progressively greater crystallinity attributed to cristobalite and tridymite. However, these historical and continued present day categorizations of this given crystalline state may have overstated the inherent crystallinity of these opaline structures. To confirm a crystalline state of cristobalite or tridymite versus that of opal-A, opal-CT, and opal-C, a combination of known NIST reference materials (1878a quartz and 1879a cristobalite) are used as internal standards to observe alpha to beta and beta to alpha transition states using Thermal-XRD and TGA-DSC.
