Fused Silica Particle Size Guide
Mesh, F grade and millimetre band are three ways buyers describe the same material. Send the name you use in production and, if you have it, the sieve analysis.

Buyers name size as mesh, as an F grade such as 100F or 325F, or as a millimetre band. Send the name you use in production and, if you have it, the sieve analysis.
Several standard sizes are available, and particle size can be made to the customer’s requirement.
What to include in your inquiry
- Grade: A grade or B grade
- Form: sand, grains or powder
- Target particle size or mesh range
- SiO₂ target and impurity limits, if you have them
