Graphite Saggers

Maintains precise shape and integrity even under prolonged exposure up to 2200°C, preventing warping that can cause batch loss or furnace damage. Ensures consistent stacking and spacing for uniform heat treatment.

Made from ultra-high purity graphite (99.99%+) with low ash content. This drastically reduces the risk of metallic impurities migrating to your sensitive products, safeguarding their chemical composition and final properties.

Withstands rapid furnace heating and cooling cycles without cracking or spalling. This enhances operational flexibility, reduces downtime between batches, and extends the usable lifespan of the sagger significantly.

Available in a wide range of standard and custom sizes, wall thicknesses, and configurations. We tailor saggers to maximize your furnace load, improve gas flow, and optimize thermal uniformity for your specific product geometry.

Exceptional resistance to oxidation (in suitable atmospheres) and thermal stress translates to more firing cycles per sagger. This reduces consumable replacement frequency, lowering your overall cost per batch and improving production efficiency.
