Frequently Asked Questions
Why choose a 99% alumina crucible for high-temperature sintering? How does a reliable manufacturer ensure zero contamination?
With ≥99% Al2O3 purity, a bulk density of 3.9 g/cm3 , and compressive strength of 2082 MPa, 99% alumina crucibles provide exceptional thermal shock resistance and chemical stability under both oxidizing and reducing atmospheres. As an experienced ceramic manufacturer, INNOVACERA strictly controls material purity and firing density to prevent chemical reactions or molten metal erosion during the high-temperature calcination of PZT, battery cathode materials, and electronic ceramics.
Can I order custom 99% alumina crucibles for specific furnace setups? What factors determine the wholesale price?
Yes, we support custom designs including cylindrical, conical, rectangular boats, and specialized wall thicknesses tailored to your thermal gradient and batch capacity needs. The unit price is primarily determined by dimensions, structural complexity, tolerance precision, and batch quantity. Contact our technical sales team for sample validation and a fast custom quote.
