High-strength Silicon Carbide 90 Product Overview
Custom Specification Graphite Petroleum Coke (GPC) with Controlled Nitrogen is a high-performance carbon additive designed for industries requiring precise control over nitrogen and carbon levels during high-temperature operations. This product is made by calcining petroleum coke at ultra-high temperatures, which enhances its fixed carbon content and ensures a stable graphitic structure while maintaining low levels of nitrogen, sulfur, and ash.
The controlled nitrogen content helps avoid contamination during the carburizing process and other sensitive applications. This custom-grade GPC is ideal for steelmaking, ferroalloy production, and other advanced industrial processes that demand reliable and precise material properties. Its stable carbon content and tailored nitrogen specifications make it highly suitable for processes that require minimal nitrogen interference in molten metal.
