Tungsten Top Hat Single Crystal

Goodfellow offers 15 variations of Tungsten Top Hat Single Crystals within its range of high-quality single crystal products. These precisely oriented single crystals boast exceptional purity and lack of grain boundaries, making them ideal for applications in fundamental materials research and as monochromators or analyzers for x-rays and neutrons. Their controlled crystallographic orientation also suits them to investigating anisotropic physical properties and as substrates for epitaxial thin film growth. With orientations ranging from (100) to (111), Goodfellow's Tungsten Top Hat Single Crystals facilitate diverse experimental investigations across disciplines like physics, chemistry, and materials science.
