Key characteristics

• High temperature resistance, radiation shielding, insulation, lubrication, plasticity, chemical stability
• Customizable expansion ratio and purity (e.g., ultra-low sulfur, ultra-fine, high purity)
• Trace elements controllable

Applications

Steel/metallurgy, petroleum/chemical, machinery, aerospace, nuclear; also stealth and flame-retardant materials.
