ColorWhiteSize300-6000mesh
BY-1250 is a white calcined kaolin powder with a stated 300–6000 mesh size range. Its oxide composition provides a practical basis for an industrial mineral enquiry, while any proposed paper, mortar or cement application needs a specification matched to that particular process.
Calcined kaolin with an oxide profile
The BY-1250 composition includes 42% Al2O3 and 52% SiO2, alongside 0.5% Fe2O3, 0.5% K2O and 1.5% TiO2. These constituent values support a composition-led comparison of the calcined clay; they do not establish a particular degree of reactivity or a finished-product strength result.
Define the fineness you actually require
A 300–6000 mesh range is a broad selection envelope rather than a single particle-size specification for BY-1250. Before ordering the kaolin, identify the required fineness, sieve or measurement convention and permitted distribution so the delivered material can be evaluated against a clear target.
- Physical form
- BY-1250 is a white powder produced using a calcined-kaolin technique.
- Moisture criterion
- The stated moisture content is 0.5%; agree the applicable test method and batch limit.
- Available selection
- The Whiteness option is 90; confirm its measurement basis for the intended end product.
Qualify paper and cement uses separately
For a paper formulation, request the kaolin specification relevant to the chosen coating or filling process. For concrete, mortar or cement evaluation, obtain application-specific test evidence before treating BY-1250 as a reactive metakaolin replacement; the material name alone does not verify pozzolanic performance.
Choose the BY-1250 trial around a defined oxide profile and fineness requirement, with the end-use acceptance criteria established before a paper or cement-system qualification begins.
