Barium Fluoride (BaF₂) Sputtering Targets
Purity: 99.99% | Size: 4” | Thickness: 0.125”
Sputtering is a proven method for depositing thin films onto diverse materials and substrate shapes. Using sputter targets, the process is highly repeatable and scalable—from small R&D projects to medium- and large-scale production. Chemical reactions can occur on the target surface, in-flight, or on the substrate depending on parameters, providing precise control over film growth and microstructure.
Applications:
-
Thin-film deposition on substrates such as silicon wafers.
-
Semiconductor etching where high anisotropy is required.
-
Material analysis, including secondary ion spectroscopy (SIMS) for trace impurity detection.
-
Space applications: sputtering contributes to space weathering on airless bodies like asteroids and the Moon.
About Barium Fluoride (BaF₂):
BaF₂ is a transparent crystalline compound effective in the 10–20 µm infrared range. It is widely used in aluminum metallurgy, enamel and glazing frit production, and welding agents. In aluminum refining, BaF₂ acts as an additive to achieve bright reflective surfaces through chemical polishing. It is also critical in flux brazing of aluminum alloys by removing oxide layers.
