SiO2 Silica Quartz Single Crystal Wafers & Substrates - Optical Grade 99.99% Pure

About This Product

For the scientists, researchers, and engineers out there working with high-precision materials, these SiO2 silica quartz single crystal wafers are the real deal.

We're talking optical grade purity here - 99.99% pure quartz with hexagonal crystal structure (a=4.914 Å, c=5.405 Å if you're into those details).

These wafers are grown using the hydrothermal method, which gives you that perfect crystalline structure needed for demanding applications.

The material properties are impressive - hardness of 7.0 Mohs, density of 2.684 g/cm3, melting point at 1610°C with a phase transition point at 573.1°C.

They're ideal as substrates for thin film deposition, optical applications, or as microwave filters in wireless communication systems.

MSE Supplies offers both standard and custom-made quartz wafers and substrates, so you can get exactly what your project requires.

The specifications are professional-grade too - you can get Y, X, Z, AT or ST cuts with the cut angle rotated to any value between 30-42.75 degrees upon request.

The polished surfaces can be epi-ready on one or both sides with Ra working area covering the wafer diameter minus 3mm edge exclusion.

The quality control is tight with no chips in the working area and strict limits on pits and scratches.

Whether you're in research, development, or manufacturing, having reliable, high-quality quartz wafers is essential for consistent results.
