A nickel crucible is a laboratory vessel used for high-temperature fusions (such as sodium peroxide) and melting samples of iron alloys, clays, and slags. Offering high resistance to dilute alkalis at a low cost, it can safely withstand temperatures up to 600°C to 1000°C depending on the purity and design.
Because nickel can oxidize at higher temperatures and is vulnerable to acidic or sulfur-heavy compounds, these vessels require careful application. If you are looking to purchase one for your lab, sizes typically range from 20 mL to 100 mL.
