High-purity graphite blocks can be divided into isostatic graphite blocks and vibration-molded graphite blocks according to their molding processes. The differences between them are as follows:1. Molding principle: Isostatic pressing uses liquid or gas media to evenly transmit pressure and uniformly pressurize the powder placed in a high-pressure container from all directions. Vibration molding uses mechanical vibration to gradually compact the graphite powder in the mold.2. Structural properties: Isostatically pressed graphite blocks have a uniform and dense structure, good isotropy, and usually high density, which can achieve high mechanical strength. Vibration-molded graphite blocks are generally medium-coarse particle structures, which are relatively poor in density and isotropy.3. Production efficiency: The isostatic pressing process is relatively complex and the production cycle is long. Vibration molding has relatively high production efficiency and can complete the molding process of graphite blocks quickly.
