Small calculations decide whether three suppliers’ quotations can be compared at all: which sizing standard a grit number belongs to, whether an assay is written on the oxide or the element basis, and whether the specification names the method the numbers were measured by. Each is done here, with the caveats attached.
- Abrasive grit cross-referenceConvert between Chinese W-grades (GB/T 2481.2), JIS R6001 grit numbers and FEPA, with the D50 each standard actually specifies and the caveats that make a grit number unquotable on its own.
- Oxide ↔ element converterConvert a COA assay between the oxide and the element in both directions — Fe₂O₃/Fe, Sc₂O₃/Sc, Y₂O₃/Y, TiO₂/Ti, SiO₂/Si — with the factor derived from atomic masses and checked against your specification limit.
- RFQ specification builderAnswer a short series of questions about what you need and get a paste-ready specification block: purity as a numeric band, D50 with tolerance and measurement method, trace metals on the element basis, Incoterms and production-lot COAs.
- SOFC electrolyte conductivity: YSZ vs ScSZEvery reported YSZ and ScSZ conductivity figure from our electrolyte comparison, plotted with its measurement conditions, its literature spread and the study where ScSZ lost — plus the ASR arithmetic that sets your electrolyte thickness.
Every figure these tools return is traceable to a published standard or to an atomic mass, and each page shows which. Nothing is estimated on your behalf.
