Zentek’s Albany Graphite provides nuclear suitability testing results

Zentek’s (ZTEK) Albany Graphite shared on update on its Critical Minerals Innovation Fund grant-funded activities, further to its release dated September 22, 2025. AGC, in collaboration with American Energy Technologies Company, has completed additional material characterization tests that confirm nuclear specifications continue to be met. The findings suggest that ultra-high purity Albany graphite could be well suited for use in the nuclear energy industry. Highlights: Air Jet Sub-Sieve Analyzer Yield: The test confirmed that Albany graphite meets the specified particle size distribution and D50 required for nuclear applications. Significance: Achieving the proper particle size ensures the graphite can be processed efficiently and maintains consistent performance during manufacturing. This is critical for the reliability and integrity of nuclear-grade graphite components used in reactor environments.Compressibility: Albany graphite demonstrated high compact density and low elastic expansion after compression. Significance: These properties are essential for maintaining the structural integrity and long-term stability of matrix graphite used in nuclear reactors, especially those of pebble bed type. High compact density and minimal expansion ensure components can withstand the extreme conditions present in nuclear operations. Four-Point Resistivity: The material exhibited low electrical resistivity, indicating a high degree of graphitization. Significance: A high graphitization level enhances thermal and electrical conductivity, which is vital for efficient and safe reactor performance, especially in pebble-bed and other advanced nuclear reactors. This property supports the overall efficiency and safety of nuclear energy systems. Coefficient of Friction: Albany graphite met or exceeded industry standards for frictional performance. Significance: Reliable coefficient of friction values help ensure that graphite components resist wear, endure mechanical motion within auxiliary reactor support systems, and have longer service lifespans. This contributes to lower maintenance requirements and improved operational reliability. Collectively, these results demonstrate that Albany graphite not only meets but often exceeds the stringent requirements for nuclear-grade graphite. This comprehensive performance supports its suitability for demanding nuclear industry environments, reinforcing Albany graphite’s potential as a safe, reliable material for nuclear energy applications.
