xCell Lab 4N (99.99%) Silicon Dioxide (SiO₂) Pieces Evaporation Materials
High-Purity Silica for Optical, Electronic, and Structural Coatings
General Description
Cell Lab 4N (99.99%) Silicon Dioxide (SiO₂) Pieces are premium-grade evaporation materials widely used in thin-film deposition, optical coatings, and semiconductor applications.
Also known as silica, SiO₂ occurs naturally as quartz and is one of the most abundant oxides on Earth. It is an essential material across industries — from microelectronics and energy research to pharmaceutical and structural engineering.
SiO₂ coatings are among the most widely used ceramic coatings, providing excellent thermal stability, dielectric strength, and chemical resistance. This makes them ideal for battery research, magnetic thin films, and optical material protection.

FAQ
Q1: What is the difference between SiO₂ and SiO evaporation materials?
SiO₂ forms insulating, transparent coatings, whereas SiO provides semi-conductive, stress-relief layers in multilayer films.
Q2: What crucible material is best for SiO₂ evaporation?
Al₂O₃ crucibles are recommended for maintaining purity and preventing contamination.
Q3: Can I order SiO₂ pieces in custom shapes or sizes?
Yes, Cell Lab provides custom dimensions and purity levels to suit specific deposition systems.
Q4: Is SiO₂ compatible with E-beam evaporation?
Yes, SiO₂ has excellent E-beam compatibility with graphite or tantalum liners for clean deposition.
Shipping & Return
xReturns Policy
You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly.
