Who We Are
A Silicon Materials Supplier Built for Industrial Supply
FerrumX manufactures, processes and exports silicon carbide and selected silicon-based materials for industrial buyers who require defined chemistry, controlled particle size and dependable order documentation.
Our core offer is black and green silicon carbide in lump, grain, grit and powder forms. We work with abrasive, refractory and metallurgical customers from specification review and sample evaluation through batch testing, packing and shipment.
Rather than presenting every requirement as a standard grade, we review the intended application, acceptance limits and commercial conditions before recommending a product route.

Why Choose FerrumX?
Our Values
Our values guide how we manufacture, test, protect customer information and support international supply. They are working principles applied throughout specification review, production and delivery.
Responsible Operations
We work to maintain safe production practices, responsible resource use and clear operating controls. Environmental, health and safety requirements are treated as part of manufacturing discipline—not as separate marketing claims.
Reliable Supply Planning
We review material availability, production capacity, processing requirements and delivery conditions before confirming an order. This helps buyers plan regular demand and discuss unexpected requirements with realistic expectations.
Consistent Batch Quality
Customer products depend on repeatable raw-material performance. We align chemistry, particle size, test method and acceptance limits, then provide the batch documentation agreed for the shipment.
Application-Led Development
When a standard grade does not fit, we work with the customer to review the application, processing route and target values. Any custom solution is evaluated against technical feasibility and measurable acceptance criteria.
Respect for Confidentiality
Specifications, formulations, process information and commercial requirements shared for product evaluation are handled as confidential business information and used only to support the agreed customer project.
International Supply Support
We support overseas buyers with specification communication, export packing, documentation and shipment coordination. Requirements are reviewed for the customer’s destination rather than treated as a one-size-fits-all order.

FAQ
FerrumX manufactures silicon-based and nitride materials for industrial applications worldwide. Our core product lines include: (1) Silicon Carbide — black SiC (70–98%), green SiC (97–99.5%), micronized powder (F230–F1500), grit series (F8–F220), metallurgical grade (pellets & briquettes), and refractory grade; (2) Nitride Materials — silicon nitride powder (Si₃N₄), ferrosilicon nitride, ferrochrome nitride, and silicon manganese nitride; (3) Refractory Products — tap hole clay, trough & slag runners, and slide gate plates. Total annual SiC production capacity is 120,000 tons.
FerrumX products serve five major industrial sectors: (1) Steelmaking & Metallurgy — SiC deoxidizer and Si/C alloying additive, FeSiN for cast iron nucleation, LD/BOF energy booster; (2) Refractories — SiC for tap hole clay, trough runners, slide gate plates, kiln furniture, blast furnace linings; (3) Abrasives & Surface Finishing — SiC grains and powders for grinding, polishing, sandblasting; (4) Advanced Ceramics — Si₃N₄ for high-performance ceramic components and thermal management; (5) Power Electronics — SiC and Si₃N₄ substrates for EV power modules, semiconductor devices, and renewable energy systems.
