Contamination is a major risk for precision sintering. High purity graphite columns reduce ash content and outgassing, protecting your batches from impurity pollution. Jiecheng Graphite manufactures high-purity graphite columns for semiconductor, ceramic and new energy thermal processes.

Key Features Ultra-low ash content minimizes volatile release under vacuum. High density and compact structure resist slag erosion and slow oxidation. High compressive strength avoids deformation under long-term high-temperature load. Fine grain isostatic graphite offers stable structure and consistent performance across every column.

Graphite Column

Typical Applications

  • Semiconductor component sintering furnaces
  • Lithium battery material sintering equipment
  • Ceramic substrate and ceramic target sintering
  • Precious material vacuum thermal treatment
  • PECVD and other electronic thin film processing furnaces

For processes with strict purity requirements, high purity graphite columns are the standard choice. Jiecheng Graphite supports custom diameter, length and connection structure, with full inspection before shipment.
