Zero-Porosity Slip-Cast Alumina for Contamination-Free Calcination
Alumina Cylindrical Crucibles
Stop ruining your battery materials and high-purity melts with flaking dry-pressed ceramics. Our factory-direct cylindrical crucibles are manufactured using traditional slip-casting, delivering a 0% water absorption structure that guarantees zero particle slagging up to 1700°C. Secure industrial-grade reliability while bypassing standard US distributor markups.
Key Features of Cylindrical Crucibles
Zero-Porosity Slip-Casting
We reject mass-produced dry-pressing. Our traditional slip-casting method delivers 0% water absorption. This ultra-dense structure physically prevents sample penetration and guarantees completely slag-free calcination.
Up to 99.95% Purity Control
Select from cost-effective 99.1%-99.4% grades for general metallurgy, or upgrade to ultra-pure 99.95% for lithium battery material synthesis, ensuring ppm-level contamination control without carbon residue.
1750°C & Lead Corrosion Defense
Engineered for continuous operation at 1700°C, with tested peak endurance up to 1750°C. Delivers exceptional defense against high-temperature acid/alkali attacks and heavy metal (Lead) corrosion.
Factory-Direct Economics
Stop paying 300% markups to standard lab catalog distributors. Source your cylindrical inventory directly from our manufacturing base to secure true industrial-grade reliability at uncompromising factory prices.
Factory Inventory & Specs
Standard Dimensions & Slip-Cast Tolerances
We stock a wide range of standard sizes. All dimensions are Outer Diameter (OD). Please note: To achieve our signature 0% water absorption, our traditional slip-casting process involves natural thermal shrinkage. This results in standard industrial tolerances (ranging from ±1mm to ±5mm depending on the overall size).
Rapid Dispatch & Wholesale RFQ
We keep our most frequently requested cylindrical sizes in stock for immediate lab checkout (dispatched in 1-2 days). For bulk industrial orders or specific dimensions from the complete table below, please submit an inquiry for a factory-direct wholesale quote.
