Buyer Guide
Buyers should not reduce grade selection to purity alone. In practice, industrial and electronic grade IBIB are compared by purity target, moisture, acidity, metal ion control, application risk, and documentation expectations.

Decision Basis
Based on Aldoryx COA data. Typical values from recent production batches.
| Parameter | Industrial Grade | Electronic Grade |
|---|---|---|
| IBIB Content | ≥99.5% (typical 99.48–99.59%) | ≥99.7% |
| Color (Pt-Co) | ≤15 (typical 10) | ≤10 |
| Acidity | ≤0.01% (typical 0.003%) | ≤0.005% |
| Moisture | ≤0.05% (typical 0.03%) | ≤0.03% |
| Na⁺ (ppb) | ≤200 (typical 40–76) | ≤100 |
| K⁺ (ppb) | ≤200 (typical 85–93) | ≤100 |
| Density (20°C) | 0.84–0.86 g/cm³ | 0.84–0.86 g/cm³ |
The decision is application-driven, not price-driven.
Your application is coatings, inks, or adhesives where standard purity (≥99.5%) and routine impurity levels are sufficient. Most automotive, wood, and plastic coating formulations fall here.
Your application involves semiconductor-adjacent processes, electronic cleaning, or precision coatings where tighter metal ion control (Na⁺/K⁺ below 100 ppb) and lower moisture are required for qualification.
A solvent at 99.6% purity with Na⁺ at 180 ppb may fail electronic-grade qualification. Conversely, 99.5% purity with Na⁺ at 50 ppb may pass. Review the full COA, not just the headline number.
Electronic-grade buyers typically require batch-specific COA with trace metal analysis before qualification. Industrial-grade buyers usually accept standard COA with purity, moisture, acidity, and color.
Both grades are produced on the same line. Electronic grade is achieved through tighter process control and additional QC screening, not a separate facility.
Request a recent COA for the grade you are considering. If the actual values meet your internal specification, proceed to sample. If not, discuss whether the other grade is a better fit.
