Grafito natural en hojuelas
El grafito natural en escamas es la variedad geológica más común de grafito natural, conocida por su distintiva morfología laminar (en forma de escamas), excelente lubricidad y alta estabilidad térmica.
Protección catódica
Corrosion Prevention and Infrastructure Protection
Cathodic protection systems are critical for preserving the integrity of pipelines, storage tanks, marine structures, and other buried or submerged assets. These systems rely on controlled electrochemical reactions to prevent corrosion, requiring materials that provide consistent conductivity, durability, and long-term performance in challenging environments.
Asbury Advanced Materials supplies a full range of carbon-based backfill materials engineered to optimize cathodic protection systems. Our products are designed to improve current distribution, reduce resistance, and extend anode life, supporting reliable corrosion protection across a variety of applications.
With expertise in particle size control, density, and resistivity, Asbury delivers tailored solutions for both shallow and deep well systems, ensuring efficient performance in diverse field conditions.
Solving Real-World Cathodic Protection Application Problems for Over a Century
Cathodic protection systems must overcome several operational and environmental challenges:
- High anode-to-earth resistance limiting current flow
- Uneven current distribution reducing protection effectiveness
- Premature consumption of sacrificial anodes
- Gas blockage and drying within the backfill column
- Loss of borehole integrity or collapse over time
- Difficulty maintaining long-term system efficiency in remote or buried environments
Addressing these challenges requires materials that enhance conductivity while maintaining structural and environmental stability.

Key Use Cases for Carbon in Cathodic Protection
Carbon materials play a central role in improving cathodic protection system performance:
Anode Backfill Enhancement
Carbon backfill materials such as calcined petroleum coke, fluid coke, and metallurgical coke increase the effective anode surface area. This allows current to be distributed more efficiently from the anode to the surrounding environment.
Reduced Anode Consumption
Because carbon materials can oxidize in place of the metallic anode, they help reduce the rate of anode consumption, extending system life and reducing maintenance requirements.
Lower Electrical Resistance
Low-resistivity carbon backfills provide an efficient electrical pathway, improving current flow between the anode and the surrounding soil or electrolyte.
Improved Contact and Current Distribution
Optimized particle size and density improve contact between the anode and backfill, ensuring consistent current transfer and system performance.
System Stability and Longevity
Carbon backfills help prevent gas blockage, reduce drying tendencies, and maintain borehole integrity, supporting long-term operational stability.
