描述

锆坩埚产品介绍

锆(Zirconium, Zr)是一种银白色金属,密度为 6.52 g/cm³,具有较小的中子吸收截面和较高的熔点(1855°C),在高温下具备优异的机械强度。因此,锆坩埚广泛用于金属熔炼,性能优于多数替代材料。

尽管锆坩埚的初期成本高于镍坩埚,但其出色的耐用性带来更长的使用寿命和更高的性价比。锆材料还拥有极强的耐腐蚀性能,其表面自然生成的氧化锆(ZrO₂)保护层能抵抗几乎所有酸性腐蚀,唯独不能接触氢氟酸(HF)。此外,锆不像铂那样具有催化作用,因此更适合用于高温金属处理。

常见问题

Sputtering targets are materials used in thin-film deposition processes to create coatings on substrates. They are used in industries like semiconductors, optics, photovoltaics, and electronics.

Evaporation materials are used in Physical Vapor Deposition (PVD) processes, where materials are heated and evaporated to form a thin film on a substrate. These are critical for applications in optics, wear protection, and decorative coatings.

Boat crucibles are used as containers for evaporation materials during PVD processes. They help to uniformly evaporate materials onto the substrate for thin film formation.

Sputtering uses energetic particles to eject material from a target, while evaporation involves heating a material until it vaporizes and deposits on a substrate. Both are common methods in Physical Vapor Deposition (PVD) for creating thin films.

Consider the material composition, purity, target size, and application-specific requirements such as the thickness and uniformity of the film.

Yes, we offer customized sputtering targets, evaporation materials, and crucibles to meet specific customer requirements for size, material composition, and purity.

Yes, we can assist in selecting the most suitable material based on your application, whether it’s for optical coatings, semiconductor fabrication, or decorative finishes.

Yes, we offer both bulk and small quantities of sputtering targets, evaporation materials, and spherical powders to support research, prototyping, and development projects.
