Step-by-Step: The CRAC Manufacturing Excellence
1. Raw Material Synthesis and Preparation
Everything begins with high-purity nano-zirconia powder. At CRAC, we utilize premium Nano Zirconia Beads raw materials. The powder is precisely mixed with stabilizers (typically Yttria) and binders to create a uniform slurry. This ensuring the final Zirconia Balls have a homogenous internal structure.
2. Forming and Shaping
Using advanced rolling or isostatic pressing techniques, the slurry is transformed into spherical "green" bodies. Achieving perfect sphericity at this stage is crucial for ensuring stable movement within the grinding chamber, reducing internal friction and heat generation.
3. High-Temperature Sintering
The green balls are fired in high-tech kilns at temperatures exceeding 1450°C. During this process, the particles fuse, and the material reaches its theoretical density. Our precision-controlled cooling rates are vital to avoid internal micro-cracks, ensuring our Zirconia Balls maintain their legendary toughness.
4. Precision Polishing and Sorting
Post-sintering, the balls undergo a surface treatment to achieve a mirror-like finish. This minimizes mechanical wear on the grinding machine parts. Finally, automated sorting systems ensure that every batch meets strict diameter tolerances.
