Sapphire Wafer 6inch C Axis to M Axis Orientation 350um Thickness

Sapphire Wafer 6inch C Axis to M Axis Orientation 350um Thickness

Product Description

Sapphire wafers are single‑crystal substrates grown from high‑purity aluminum oxide (Al₂O₃) via processes such as the Kyropoulos (KY) and Heat Exchanger Method (HEM). Their molecular structure consists of three oxygen atoms and two aluminum atoms covalently bonded in a hexagonal lattice. This structure endows sapphire wafers with a range of superior properties, making them a key material across multiple high‑precision and cutting‑edge fields.

Product Highlights:

* Common crystallographic orientations include C‑plane (0001), A‑plane (11‑20), and R‑plane (1‑102); the choice of orientation tailors optical, mechanical, and epitaxial behavior for specific devices.

* Typical optical transmission spans the near‑UV to mid‑infrared (approximately 0.19–5.5 μm), with high transparency in the 0.3–5 μm range, supporting applications in optics and optoelectronics.

* Mechanical and thermal properties include a Mohs hardness of 9, high strength and wear resistance, and a melting point ~2050°C, enabling performance under extreme environments.

* Chemical stability is excellent—resistant to most acids and alkalis—with notable attack only by HF, phosphoric acid, and molten KOH at elevated temperatures.

* Representative applications: LED substrates (GaN on sapphire), infrared and laser windows, optical components, and wear‑resistant covers in consumer electronics.
