CheomdanLab Co., Ltd.

Sustainable Silicon Nitride Ceramics for Next-Generation Mobility and Advanced Materials

Specialization

Advanced Ceramics Resource-Circulating Materials

Keywords

Silicon Nitride (Si₃N₄)
Ceramic Ball Bearings

CheomdanLab specializes in developing silicon nitride (Si₃N₄) ceramic materials for electric vehicles, semiconductors, and renewable energy applications.
The company’s SRBSN (Sintered Reaction-Bonded Silicon Nitride) technology enables low-cost, high-performance ceramic components using recycled silicon scrap.
Their core products include Si₃N₄ ceramic ball bearings and heat-dissipating substrates for high-speed motors, inverters, and thermal management modules
The process significantly reduces carbon emissions (–67.4%), energy consumption, and raw material costs, establishing a closed-loop, resource-circulating production system.

(1) Owned Technology

SRBSN Ceramic Process: Uses waste silicon (Si) as feedstock instead of high-cost Si₃N₄ powder (USD 200/kg → USD 5/kg).
Proprietary sintering system achieving high fracture toughness, wear resistance, and corrosion stability.
Possesses 4 tons/month production capacity (2025) for high-purity Si₃N₄ reaction sintering.
Certified RoHS and REACH compliant — no hazardous substances detected.

(2) Applied Products

Si₃N₄ Bearing Balls & Blanks: For electric vehicle motors, reducers, and industrial machinery.
Si₃N₄ Powders: For heat-substrate materials and high-performance ceramics.
Ceramic Heat Substrates: For cooling systems in EV inverters, railways, and industrial energy converters.

(1) Problem Definition / Development Background

Global supply instability and high production cost limit the adoption of silicon nitride materials.
EVs and renewable systems increasingly require lightweight, corrosion-resistant ceramic components.

(2) Value Proposition / Solution

CheomdanLab’s SRBSN process enables mass production of eco-friendly ceramics using recycled silicon, achieving:
- 67.4% lower carbon emissions vs. Japanese nitridation methods.
- 80% material cost savings through waste silicon reuse.
- Equivalent physical performance to imported Si₃N₄ ceramics (Vickers hardness 1560 Hv1, density 3.23 g/cm³).
Enables Scope 1–3 carbon reduction across the entire supply chain.

Technology Leadership:
- First in Korea to commercialize recycled-silicon-based SRBSN ceramics.
- Secured domestic and international patents (Japan, China, EU) for high-tolerance Si₃N₄ manufacturing.
Cost & Sustainability Advantage:
- Reduces energy use and CO₂ emissions across production.
- Builds competitive supply chain for global bearing and thermal substrate markets.
Quality Assurance:
- Verified by Korea Institute of Production & Technology (KITECH).
- Matches or exceeds physical properties of Japanese and Chinese Si₃N₄ ceramics.

Selected for Korea Bearing Industry Association and High-Tech Bearing Center Program.
Developing mass-production line in Changwon (3 tons/month) for global supply (2026).
Preparing Series B (2026, USD 8M) for facility expansion and joint venture establishment.
Strategic partnerships: Schaeffler Group, CeramTec, NBR Motion, and domestic OEMs.

(1) PoC Progress

R&D and PoC partnerships underway with CeramTec (Germany) for Si₃N₄ heat-substrate materials.
Technical seminars and supplier audits in progress for Schaeffler Group (PPAP, APQP compliance).
Collaborative evaluation with bearing manufacturers to integrate SRBSN into next-generation EV drivetrains.

(2) Global Expansion

Plans to establish joint venture factories with capital partners in Europe and Asia for localized supply.
Target markets: EVs, semiconductors, wind energy, and aerospace components.
Long-term goal: become a global top-tier supplier of sustainable ceramic materials for advanced industries.
