How can you identify kaolinite from FTIR?
This page summarizes the recurring FTIR evidence reported for kaolinite, including the most frequent peaks, supporting functional groups, and literature-backed interpretation patterns. It is a structured evidence page, not a claim of automatic single-spectrum certainty.

Respuesta rápida
kaolinite is usually reported with a recurring pattern of peaks and functional-group evidence. The most useful approach is to cross-check at least two characteristic peaks before treating it as a match, then verify whether the full spectrum still fits the same material family.
Interpretación de picos
Materiales / grupos posibles
| Grupo funcional | Evidencia |
|---|---|
| Hydroxyl (O-H) | 66 |
| Silicon-oxygen (Si-O) | 54 |
| Silicon (Si) | 28 |
| Siloxane (Si-O-Si) | 18 |
| Metal oxygen | 14 |
| Water (H2O) | 10 |
| Phosphate (PO4) | 7 |
| Metal hydroxyl | 6 |
Lógica de espectro
The logic here is evidence aggregation: repeated literature mentions of kaolinite, repeated peak positions, and repeated functional-group associations. A strong material hypothesis should still be supported by multiple peaks that agree with each other, not by one headline band alone.
Uso en el mundo real

Errores comunes
- Llamar a una coincidencia de material demasiado pronto porque está presente un pico famoso.
- Ignorando la preparación de la muestra, cargas, oxidación, agua o aditivos que pueden cambiar el patrón aparente.
- Usando evidencia de la literatura sin verificar si su propio modo de muestreo y calidad del espectro son comparables.
Consejo de verificación
Use DSC, GC-MS o TGA para validar la hipótesis del material cuando el patrón de picos sea ambiguo o mixto.
