product_detail
For mass production sintering factories running continuous kilns, frequent sagger replacement brings extra labor cost and unplanned downtime. High-density graphite sagger is engineered to solve this pain point. Jiecheng Graphite supplies dense graphite saggers optimized for repeated long-cycle sintering conditions in new energy and advanced ceramic industries.
Core Product Features
High-density graphite sagger has a compact microstructure with minimal open porosity. Dense texture effectively blocks molten slag and fine powder from penetrating into the graphite interior, avoiding spalling and internal expansion damage. It has outstanding compressive strength, so the sagger body will not deform or sag under long-term high-temperature stacking load. The oxidation resistance is improved compared with standard graphite, slowing material loss after dozens of thermal cycles. Uniform density distribution ensures stable performance on the bottom, side wall and cover. The surface can be impregnated for extra anti-oxidation protection upon request.
Main Application Scenarios
- Large-scale continuous sintering of lithium iron phosphate and ternary battery materials
- Mass production sintering of ceramic substrates and ceramic targets
- Hard alloy powder and tungsten carbide sintering
- Rare earth permanent magnet material heat treatment
- Recyclable batch sintering processes with high cycle counts
The upfront cost of high-density graphite sagger is higher than ordinary grades, but its longer working life reduces overall production cost. We support custom inner cavity dimensions, wall thickness and matching cover machining. Our engineering team can optimize the structure to reduce thermal stress for your specific kiln model.
