What is the maximum working temperature of your fused quartz products?

Our fused quartz is rated for long-term service around 1100°C and short-term peaks up to approximately 1450°C. The softening point is about 1683°C. For vacuum or high-load applications we recommend a lower continuous temperature and thicker walls.

What is the difference between fused quartz and synthetic fused silica?

Fused quartz is made by melting high-purity natural quartz crystal sand and typically reaches 99.99%+ SiO2. Synthetic fused silica is produced from silicon-containing chemical precursors and offers lower metallic impurities and better deep-UV transmission. We help you choose based on wavelength, purity and budget.

What is the minimum order quantity for custom quartz parts?

Most custom items such as rods, plates, boats and crucibles start from 1 piece. Some standardized tubes and lab parts start from 5–10 pieces.

Why choose an ozone-free quartz tube?

Ozone-free quartz is doped to absorb short-wave UV below roughly 220 nm, which blocks the 185 nm line that generates ozone. It is used in UV lamps, heaters and curing systems where ozone would damage equipment or affect operators.

Can you manufacture quartz parts from my drawing?

Yes. We are a verified custom manufacturer offering cutting, bending, welding, grinding, drilling and polishing. Send a 2D/3D drawing with tolerances, purity grade and quantity to info@vulraquartz.com for an engineering review.
