What are dry silica microspheres used for?
Dry silica microspheres enable precise particle calibration and validation across scientific and industrial systems.
They support:
- Aerosol measurement calibration
- Semiconductor CMP slurry formulation
- Laser particle counter validation
- Atmospheric particulate testing
These particles deliver repeatable size accuracy and stable morphology across batches
How does particle size impact performance?
Particle size determines measurement resolution and calibration accuracy.
| Size Range | Primary Application | Accuracy Impact |
|---|---|---|
| 100–300 nm | Nanoparticle aerosol research | High sensitivity calibration |
| 300–800 nm | LPC and SSIS calibration | Standard instrument validation |
| 800 nm–1 µm | CMP slurry formulation | Surface uniformity control |
| 1–3 µm | Airborne particle testing | Coarse particle detection |
You should match particle size to your instrument detection range.
Why do silica microspheres outperform PSL spheres?
Silica microspheres deliver thermal stability, chemical resistance, and longer calibration life.
- Silica withstands high-energy laser exposure
- Silica maintains structure under solvents
- Silica preserves calibration integrity over time
PSL spheres degrade under heat and solvents, which reduces accuracy.

Which industries use dry silica microspheres?
Industries use silica microspheres for precision measurement and process control.
Semiconductor Manufacturing (CMP Slurry)
Silica particles enable defect reduction and surface planarization.
800 nm particles frequently support wafer polishing consistency.
Aerosol and Environmental Testing
Researchers use silica particles to simulate airborne particulate matter for instrument calibration.
Instrument Calibration (LPC, SSIS)
Labs use NIST-traceable silica standards to validate particle counters and sensors.
How should you select the right particle size?
You should select based on instrument sensitivity and test objective.
- Choose 100–300 nm → nanoparticle research
- Choose 300–800 nm → standard calibration
- Choose 800 nm–1 µm → CMP slurry use
- Choose 1–3 µm → air quality testing
Matching size improves calibration accuracy and reduces measurement error.
What ordering options are available?
You can order based on project scale and consumption rate.
- Order 1 gram → lab-scale testing
- Order bulk (1 kg+) → production or repeated calibration
- Request custom sizes → tailored specifications
Bulk orders reduce cost per test cycle.
