This short article is created to serve as a guidebook for choosing the optimal crucible for your Procedure. It clarifies the connection concerning metallic melting/Keeping operations and unique crucible attributes.
This resistance is very best imparted by both equally a consistently dense crucible product composition as well as a strong protective glaze. When your melting software will involve the use of corrosive metal therapies, you absolutely will desire a crucible featuring the right standard of protection versus these agents.
Both equally crucibles ended up break up in 50 percent for Investigation: Though the standard crucible showed brim oxidation and oxidation nests, the VAluStar™ crucible only confirmed a slight brim oxidation, which was brought on by the insulation fiber
American Components focuses on giving Alumina (Aluminum Oxide) Crucibles with a variety of Proportions and shapes; customized configurations are offered. Alumina crucibles are normally right away accessible in many volumes, like bulk quantities. American Factors can generate products to custom made technical specs by request, As well as custom compositions for professional and exploration applications and new proprietary technologies.
