A graphite grade that performs well in one hot-zone component may not be the best choice for another.
For example:
• A heater needs stable hot-state electrical resistivity and good current distribution.
• A CZ crucible support requires strength, low porosity, SiO resistance, and dimensional stability.
• A SiC PVT crucible must balance electrical resistivity, thermal conductivity, CTE, permeability, and vapor-phase stability.
• A coated susceptor requires the graphite substrate and SiC/TaC coating to work as one system.
This is why isostatic graphite selection should start from the component function and failure mode, not from a datasheet ranking.
We recently published a detailed engineering guide on how to evaluate isostatic graphite for high-temperature hot zones.

SHJ CARBON at Heat Treatment 2025 Exhibition in Moscow
— Sharing Insights on Vacuum Furnace Thermal Field Materials

During discussions with local experts, we observed a clear trend in the Russian market:

1300–1600°C vacuum furnaces dominate the mainstream.
≤1200°C furnaces remain widely used for tempering and brazing.
≥1800°C furnaces exist but serve specialized, high-value applications.

This market insight resonates strongly with our mission — delivering high-performance thermal field solutions from C/C composites to carbon felt and carbon paper.

These materials ensure:
Reliable performance under long-term thermal cycling
Energy efficiency through optimized insulation design
Custom adaptability for both standard and ultra-high temperature furnaces

We are proud to connect with partners worldwide and continue supporting industrial innovation with advanced carbon materials.
