Fire polishing is a thermal finishing process used to smooth the surfaces of quartz components by briefly exposing them to a high-temperature flame. This controlled application of heat melts microscopic surface irregularities, creating a uniform, glassy finish without altering the part’s dimensions or integrity.
Why Fire Polishing Matters
In many semiconductor and high-vacuum processes, surface roughness can lead to:
- Particle generation during deposition
- Poor film adhesion
- Contamination-related yield loss
By removing surface imperfections and restoring optical clarity, fire polishing helps ensure your components perform reliably in critical deposition environments.
