Super Graphite Crucible

Item Unit Diameter or thickness 39-75 Resistivity μΩm <= 7.5 Ash % <= 0.2 Compression strength Mpa >= 29 Bulk density g/cm3 >= 1.65 Breaking strength Mpa >= 16 Vanadium content ppm <= 10 Note: please don’t measure Vanadium content if not used for mercury tank. Graphite Crucible Performance Thermal stability: According to the quench acute thermal using conditions of graphite crucible, we specially design the production procedure, so as to ensure the reliability of product quality.Corrosion resistance: Even and fine basic design will delay the erosion of crucible.Impact resistance: Graphite crucible can bear high thermal impact, so any process can be carried out.Acid resistance: The adding of special materials will greatly improve the quality of crucible, especially its index of acid resistance, and will prolong the service lift of graphite crucible.High heat conduction: High content of fixed carbon ensures the good heat conduction, shorten the time of dissolution, and remarkably reduce the energy consumption.Control of metal pollution: The component of material under strict control will ensure that graphite crucible will not pollute the metal when dissolving.Quality stability: The process technology of forming under high pressure and quality guarantee system will fully ensure the stability.
