Description
Evaporation Crucibles
Evaporation crucibles are typically made from high-melting-point materials such as tungsten, tantalum, molybdenum, graphite, or ceramics. They provide excellent thermal conductivity and stability under high temperatures, enabling precise control of film thickness and uniformity during deposition. Available in various sizes and shapes, crucibles are easy to handle and suitable for evaporating metals, semiconductors, and ceramics. Their versatility and reliability make them essential tools in thin-film deposition.
