Why Panson Carbon
More Than a Supplier — Your Carbon Partner
We control the full chain from Ningxia's Taixi anthracite mines to your furnace — ensuring every lot meets spec before it ships with a Certificate of Analysis.
Origin-Controlled Feedstock
Direct access to Ningxia's low-ash, low-volatile Taixi anthracite. We secure feedstock before the open market, delivering tighter specification bands batch after batch.
Tailored to Your Furnace
Custom particle sizing, fixed carbon targets, and sulfur limits matched to your specific melt practice. COA issued per lot.
Vertically Integrated
Calcination, crushing, screening, and packaging all within our facility. No middlemen — consistent chemistry and bulk density every shipment.
Our Products
Premium Carbon Additives
Calcined Anthracite Coal
The workhorse recarburizer of the global steel industry. Produced from Ningxia's Taixi anthracite through gas calcination at 1,200°C+, our CAC delivers fixed carbon of 90–95% with the low ash and sulfur profiles that EAF and ladle furnace operators require for predictable carbon pickup.
Graphite Petroleum Coke
The premium choice for applications demanding ultra-low sulfur and maximum carbon purity. Graphitized at 2,500–3,000°C, our GPC achieves FC ≥98.5% with sulfur as low as 0.03% — the benchmark for ductile iron foundries and specialty steel producers who cannot tolerate sulfur-related quality defects.
Semi Coke
Produced through low-temperature carbonization at 500–750°C, Semi Coke offers an economical fixed carbon source (≥84%) with the specific electrical resistance properties essential for submerged arc furnace operations in ferroalloy production.
Calcined Petroleum Coke
Calcined at 1,200–1,400°C from select green petroleum coke, our CPC delivers FC ≥98% with uniform particle distribution — bridging the gap between economical anthracite-based recarburizers and premium GPC for applications where cost-performance balance is critical.
Silicon Carbide
A metallurgical multitool: our Silicon Carbide simultaneously contributes carbon and silicon to the melt, provides powerful deoxidation, and generates exothermic energy that reduces electrical consumption in EAF steelmaking by 10–15 kWh per ton of steel.
Ferro Silicon
The foundational deoxidizer and alloying agent for steelmaking worldwide. Our FeSi is produced in Ningxia's submerged arc furnaces, available in 72% and 75% silicon grades, with the low aluminum and calcium content that specialty steel producers demand.
Silicon Manganese
A dual-function ferroalloy delivering simultaneous deoxidation and manganese alloying in a single addition. Our SiMn combines 65–70% Mn with 15–20% Si, enabling steel producers to achieve target chemistry with fewer charge additions and tighter composition control.

About Panson Carbon
Three Decades of Carbon Mastery
When Panson lit its first calcination furnace in 1992, the carbon additive market in China was fragmented and quality was inconsistent. We saw an opportunity to bring metallurgical rigor to an industry that was still trading on relationships rather than specifications. Three decades later, that commitment to measurable quality has made us a preferred supplier for steel mills from Nippon Steel affiliates in Japan to SABIC-affiliated foundries in the Middle East.
Today our Pingluo campus processes over 100,000 tons annually through dedicated calcination, graphitization, and screening lines — each monitored by in-process sampling that catches deviations before they reach the loading dock. Every Certificate of Analysis we issue reflects actual lot testing, not nominal values.

Applications
Industries We Serve
The performance of a carbon additive is only proven in the furnace. Here is how our products perform across the industries that depend on precise carbon chemistry.
Steel and Iron Industry
In EAF steelmaking, carbon is both fuel and chemistry. Our CAC restores carbon lost during scrap melting, SiC provides exothermic deoxidation energy, and FeSi/SiMn deliver precise alloying — together reducing tap-to-tap time and improving metallic yield.
Foundry Industry
Foundry metallurgy demands precision that steelmaking rarely requires. Our GPC and CAC are matched to foundry requirements with particle sizes optimized for dissolution kinetics in induction furnaces.
Non-Ferrous Metal
Aluminum smelting, copper refining, and specialty alloy production each present unique carbon requirements — from anode-grade CPC for Hall-Héroult cells to SiC-based deoxidation in secondary metallurgy.
Chemical Industry
SiC's extreme hardness, thermal conductivity, and chemical inertness make it indispensable in high-temperature chemical processing and refractory applications.
Ferroalloy Production
Submerged arc furnaces for FeSi, SiMn, and silicon metal rely on carbon reductants with controlled sizing and low impurities for stable, energy-efficient smelting.
Electrode & Carbon Products
Carbon electrodes, cathode blocks, and conductive pastes demand consistent real density, low ash, and controlled porosity for graphite electrode and cathode manufacturing.
Global Reach
Trusted Worldwide
From our production base in Ningxia, we have built supply chains that reach six continents. Many of our export relationships began with a single trial shipment and evolved into multi-year framework agreements — a testament to the consistency our partners experience container after container.

Why Choose Us
What Our Partners Tell Their Colleagues
Quality Assurance
Every lot that leaves our facility carries a Certificate of Analysis based on actual XRF and proximate analysis results — not nominal catalogue values. Our ISO 9001 system ensures traceability from raw material receipt through calcination parameters to final packaging, so when your quality team audits our documentation, the numbers match what your spectrometer confirms on arrival.
Innovation & Technology
We invested in gas calcination technology when most Chinese producers were still using Soderberg kilns. That early adoption gave us tighter temperature control, more uniform heat distribution, and lower residual volatiles — advantages our customers measure in their own furnace performance data. Today we continue to upgrade screening, dust collection, and process monitoring systems because incremental improvements compound over thousands of tons.
Customer-Centric
Our longest-running customer relationship spans over 20 years. That kind of loyalty is not built on price alone — it comes from answering a 2 AM WhatsApp message about a shipment delay, from adjusting a particle size distribution mid-contract because their process changed, and from flying to their plant when a quality concern needs face-to-face resolution. We treat your furnace performance as our responsibility.
