Good Thermal Conductivity High Strength Industrial Flat Mouth Graphite Crucible for Laboratory

Compared to ceramic, quartz, and clay crucibles, this flat-mouthed high-purity graphite crucible conducts heat faster, heats more evenly, and offers excellent thermal shock resistance, making them less prone to cracking under temperature fluctuations; they offer greater chemical stability, resisting acids, alkalis, and metal corrosion without contaminating the melted material; the flat-mouth design allows for easier operation, broader application scenarios, and a longer service life, making them

You can choose a model based on the weight and volume of the material to be melted in a single batch, as well as the dimensions of your melting equipment. As a general rule, we recommend that the amount melted in a single batch does not exceed two-thirds of the crucible's capacity to prevent high-temperature molten material from overflowing. For small-scale experiments and jewelry melting, choose small-capacity models; for industrial batch smelting, opt for large-capacity custom models. Alternat

Never place a hot crucible directly on a cold metal surface or wet ground, as this can cause severe thermal shock and result in the crucible shattering. Use crucible tongs to remove it and place it on a dry graphite pad, refractory brick, or ceramic plate to allow it to cool naturally to room temperature.

We do not recommend mixing metals. Melting different metals can leave trace impurities, which may cause cross-contamination and affect the purity of the final product. We recommend using a dedicated crucible for each type of metal to ensure melting quality and the accuracy of experimental and production data.

The minimum order quantity is one piece for custom specifications, though general commercial terms may list a minimum of 100 Kgs depending on the specific product configuration.
