"I'm looking for a thin window material with a high melting point that is ideally, but not necessarily, glassy so an X-ray beam can pass through with minimum attenuation. The exact specs are not absolute requirements, but an ideal material would have a thickness of <=100 microns and a melting point of 1000–2000°C. Are there materials or products that you would recommend?"
Thin Double-Side Polished Sapphire Wafers for X-Ray Beam Projects
Thin double-side polished sapphire wafers are used as durable, high-temperature window materials for X-ray beam experiments, optical testing, electromagnetic characterization, and advanced materials research. Sapphire offers excellent hardness, chemical resistance, thermal stability, and optical transmission, making it a strong choice when researchers need a thin, polished substrate that can withstand demanding laboratory conditions.
A PhD researcher in chemistry requested a quote for a thin window material that could allow an X-ray beam to pass through with minimal attenuation.
UniversityWafer, Inc. recommended 3 inch 100 µm double-side polished sapphire wafers as well as fused silica substrates for X-ray beam and high-temperature window applications.

3 Inch C-Plane Sapphire Wafer Quote Request
Another researcher requested 3 inch c-plane sapphire wafers with a thickness near 0.5 mm for laboratory research. Both one-side polished and double-side polished sapphire wafers were considered for quantities of 10 and 20 pieces.
"I am looking to buy some sapphire wafers. I would like the c-plane orientation, a circular wafer with a diameter of 3 inches and thickness around 0.5 mm, although I can be flexible on the thickness. Could you provide quotations for one-side polished and double-side polished options in quantities of 10 and 20?"

Thin 3 Inch Sapphire Wafers for Electromagnetic Material Characterization
Thin 3 inch sapphire wafers are frequently used in microwave systems, RF devices, and electromagnetic material characterization because sapphire offers excellent dielectric properties, low microwave loss, high thermal stability, and exceptional mechanical strength. Double-side polished sapphire substrates provide smooth surfaces that are ideal for precision measurements and sample mounting applications.
A doctoral candidate requested the following:
"I am looking for a price for thin sapphire wafers. I saw some on your website down to 0.1 mm thick. Can be random orientation, double-side polished. For this application, I just need thin and polished. Maybe I would buy 10 to start. We will be cutting them to smaller sizes ourselves. Do you have something in stock that we could receive quickly?"
"They will be used to hold a sample in a system for electromagnetic material characterization."
UniversityWafer, Inc. quoted 2 inch and 3 inch 100 µm DSP sapphire wafers. Reference #264183 contains specifications and pricing information.
Nickel-Coated 3 Inch Sapphire Substrates
Nickel-coated sapphire wafers are commonly used as substrates for thin-film deposition, semiconductor devices, MEMS fabrication, and advanced optoelectronic applications. Sapphire provides excellent thermal conductivity and chemical stability, while nickel thin films offer superior adhesion and compatibility with additional deposited materials.
A graduate student requested:
"I am looking for 2 inch and 3 inch sapphire (0001) wafers and 4 inch silicon (001) wafers coated with approximately 25 nm of nickel using electron beam evaporation."

Applications for Nickel-Coated Sapphire Wafers
Semiconductor Devices
Nickel-coated sapphire substrates are used for the growth of GaN epitaxial layers, LEDs, laser diodes, and power electronics. The nickel layer improves adhesion and enables additional processing steps.
Optoelectronics and Photonics
Sapphire substrates coated with nickel support thin-film deposition for photodetectors, optical sensors, and optoelectronic devices. Their transparency and thermal stability make them ideal for demanding optical applications.
MEMS and Sensor Fabrication
Nickel films on sapphire are used in MEMS devices, accelerometers, pressure sensors, and microfluidic systems. Nickel can serve as a structural or sacrificial layer during fabrication.
Thin Film Deposition Research
Nickel-coated sapphire wafers provide stable, high-quality surfaces for depositing metals, oxides, and functional thin films. These substrates are commonly used in surface engineering, optical coatings, and nanotechnology research.
Why Choose Sapphire Substrates?
Single crystal sapphire (Al2O3) offers excellent hardness, chemical resistance, optical transparency, and high-temperature stability. These properties make 3 inch sapphire wafers ideal for LEDs, RF devices, microwave applications, MEMS, photonics, and semiconductor research.
