- Key result
- Form:
- solid: crystalline
- Remarks:
- lamellar, see attached ESEM (Environment Scanning Electron Microscopy) photograph
- Colour:
- white
- Odour:
- odourless
- Substance type:
- inorganic
- Conclusions:
- odourless white inorganic crystalline solid of clay mineral-like lamellar hydrocalumite-type which has been identified as technically pure calcium-hydroxo-aluminate-phosphonate-hydrate (phosphonate-hydrocalumite)
- Executive summary:
Substance "reaction mass of calcium hydrogen phosphonate and dialuminium tricalcium hexaoxide" is an odourless white inorganic crystalline solid of clay mineral-like lamellar hydrocalumite-type which has been identified as technically pure calcium-hydroxo-aluminate-phosphonate-hydrate (phosphonate-hydrocalumite). In a final production step, the phosphonate-hydrocalumite is in-situ coated with fatty acids, C16-18 (CAS No. 67701-03-5, EC No. 266-928-5).
