How can you identify quartz from FTIR?
This page summarizes the recurring FTIR evidence reported for quartz, 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.

Quick answer
quartz 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.
Peak interpretation
Possible materials / groups
| Functional group | Evidence |
|---|---|
| Silicon-oxygen (Si-O) | 51 |
| Hydroxyl (O-H) | 21 |
| Alkyl C-H | 16 |
| Silicon (Si) | 15 |
| Siloxane (Si-O-Si) | 10 |
| Carbonate | 5 |
| Metal hydroxyl | 5 |
| Metal oxygen | 3 |
Spectrum logic
The logic here is evidence aggregation: repeated literature mentions of quartz, 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.
Real-world usage
This page is designed for polymer identification, incoming-material QC, unknown plastic analysis, recycled-content review, and literature-backed interpretation of reference spectra.
Common mistakes
- Calling a material match too early because one famous peak is present.
- Ignoring sample prep, fillers, oxidation, water, or additives that can change the apparent pattern.
- Using literature evidence without checking whether your own sampling mode and spectrum quality are comparable.
Verification advice
Use DSC, GC-MS, or TGA to validate the material hypothesis when the peak pattern is ambiguous or mixed.
