How can we help address your challenges?

Issue

Inconsistent Densification in Advanced Sintering Processes
Advanced sintering techniques like Spark Plasma Sintering (SPS), Field-Assisted Sintering (FAST), and Direct Current Sintering (DCS) require powders with precise purity and particle size distribution. Inadequate materials can lead to sub-optimal density, part failure, or poor mechanical integrity.

Solution

Superior Graphite offers binderless, high-purity Beta-SiC powders with tightly controlled particle size distributions. These powders are engineered for rapid densification and high-strength part formation, ensuring reliable performance in advanced sintering applications.

Issue

Micro-Cracking and Porosity in Ceramic Matrix Composites (CMCs)
Ceramic matrix composites are highly sensitive to internal porosity and micro-cracks, which can compromise structural integrity and thermal performance—especially in aerospace and high-temperature environments.

Solution

Our domestically synthesized Beta-SiC features fine particle size and high compatibility with SiC fiber morphologies. This enables deep infiltration into fiber interstices and supports low-temperature sintering, reducing porosity and enhancing the mechanical resilience of CMCs.

Issue

Supply Chain Risk and Material Traceability
Global supply chain disruptions and reliance on foreign-sourced materials pose risks to production continuity and compliance with domestic sourcing standards. Traditional Acheson production methods are energy intensive, raising sustainability concerns.

Solution

Superior Graphite manufactures Beta-SiC in Kentucky, USA, ensuring a secure, traceable, and ethically sourced supply of critical ceramic materials. This supports domestic manufacturing initiatives and reduces exposure to geopolitical risk. Our proprietary High Temperature Fluidized Bed process reduces energy consumption up to 75% compared to Acheson methods.
