LUOYANG, China — TRUNNANO (Luoyang Tongrun Nano Technology Co., Ltd.), a National High-Tech Enterprise with over 12 years of experience in advanced nanomaterials, announced a strategic expansion of its business scope, extending from its established expertise in nanomaterials to the research, development, and production of advanced ceramic products. This strategic move, which began in 2024, directly responds to the growing global demand for high-performance materials capable of operating under extreme conditions in the semiconductor, new energy, and aerospace sectors. Leveraging more than a decade of experience in nanoscale material control, TRUNNANO is systematically building a complete value chain from powder to component, focusing on silicon carbide series, nitride composite systems, and oxide precision ceramics. Under the leadership of CEO Roger Luo, the company is committed to solving engineering challenges in industrial settings through solid process breakthroughs, positioning TRUNNANO as a comprehensive materials solution provider for global customers.
TRUNNANO advanced ceramics — from powder to component for extreme industries.
The Strategic Logic Behind Advanced Ceramics
Advanced ceramics, also known as high-performance ceramics or engineering ceramics, are based on inorganic non-metallic materials such as alumina (Al₂O₃), silicon nitride (Si₃N₄), silicon carbide (SiC), and boron nitride (BN). Unlike traditional ceramics, which are primarily valued for their aesthetic or basic functional properties, advanced ceramics are engineered with specific mechanical, thermal, electrical, or chemical properties to perform reliably under extreme conditions—including high temperatures, corrosive environments, and high mechanical stress.
Nanotechnology is reshaping ceramic manufacturing from the ground up. By introducing nanoscale reinforcing phases—such as carbon nanotubes or boron nitride nanosheets—into ceramic matrices, fracture toughness and thermal properties can be significantly enhanced. TRUNNANO's 12-year expertise in nanoscale material control provides a unique foundation for this expansion.
TRUNNANO's entry into advanced ceramics is built on a clear understanding of the value chain. Advanced ceramic performance depends not only on forming and sintering processes but also critically on raw material powder purity, particle size distribution, and crystal form. This upstream understanding allows TRUNNANO to control final product microstructure from the earliest development stages—a capability built on more than a decade of nanomaterials experience. As CEO Roger Luo stated: "Based on 12 years of experience in nanomaterials, we optimize the 'genes' of powders from the source, precisely matching the stringent requirements of wear resistance and thermal conductivity in the new energy and semiconductor fields. We are committed to solving engineering challenges in industrial settings through solid process breakthroughs."
Advanced ceramics applications — semiconductor, new energy, and aerospace industries.
A Natural Step Forward: Strategic Deepening, Not Diversification
TRUNNANO's expansion into advanced ceramics is not a business pivot but a strategic deepening of an existing capability. The company was founded in 2014 and became a National High-Tech Enterprise in 2018. Since 2015, TRUNNANO has maintained a dedicated industrial ceramics R&D laboratory, and by 2017, industrial ceramics had entered mass production.
This strategic move is built on a solid foundation:
2014 – Founded, focusing on nanomaterials R&D and sales
2015 – Established first industrial ceramics R&D laboratory
2016 – Achieved ISO 9001 certification
2017 – Industrial ceramics entered mass production; international expansion began
2023 – Established New Materials Research Institute
2024–2025 – Launched European R&D center construction; significantly expanded advanced ceramics portfolio
What sets TRUNNANO apart is its control over materials at the "source powder" level—engineering particle properties from the ground up. This precision is critical when producing advanced ceramics, where purity, particle size distribution, and crystal form are non-negotiable. Unlike companies that focus only on downstream manufacturing, TRUNNANO controls the entire chain from raw material synthesis to finished ceramic components, ensuring consistency, quality, and reliability at every stage.

Three Technology Pillars: Core Business Portfolio
TRUNNANO's advanced ceramics business is organized around three core technology pillars, each addressing specific industrial requirements.
Silicon Carbide Series
TRUNNANO's silicon carbide portfolio includes Reaction-Bonded Silicon Carbide (SiSiC), Pressureless Sintered Silicon Carbide (SSiC), and Recrystallized Silicon Carbide (RSiC).
In February 2026, TRUNNANO announced a significant breakthrough in Reaction-Bonded Silicon Carbide (SiSiC) manufacturing. After years of process optimization, the R&D team overcame three critical technical challenges: raw material ratio optimization—achieving uniform nanoscale dispersion of α-SiC powder and high-purity carbon powder to construct a carbon/silicon carbide composite skeleton with controlled porosity; high-temperature sintering control—precise temperature management within the 1650°C–2000°C range under vacuum or inert atmosphere to ensure uniform molten silicon penetration; and free silicon content control—stabilizing free silicon content within the optimal 8%–15% range through carbon-silicon ratio and siliconizing process optimization.

Nitride Composite Systems
In October 2025, TRUNNANO launched silicon nitride-bonded silicon carbide composites, combining the wear resistance of silicon carbide with the fracture toughness of silicon nitride. These materials offer exceptional thermal shock resistance, high strength, and wear resistance, making them ideal for kiln furniture in non-ferrous metallurgy and ceramics industries.
In January 2026, TRUNNANO introduced a silicon carbide-silicon nitride composite crucible featuring a nano-boron nitride (BN) coating. This "matrix composite + nano-coating" dual design solves adhesion and corrosion challenges that have long plagued conventional silicon carbide and mullite crucibles. The nano-boron nitride coating provides a non-wetting, chemically resistant barrier that prevents molten metal and slag from adhering to the crucible surface. Applications include high-temperature sintering of lithium battery cathode materials, rare earth permanent magnet preparation, electronic ceramics, and specialty alloy production.
Oxide Precision Ceramics
TRUNNANO produces high-purity alumina, zirconium oxide, quartz, and mullite products serving wear-resistant components, electrical insulation parts, and high-purity process environments. In April 2026, TRUNNANO launched KH570 surface-modified spherical alumina, offering superior thermal management performance and interfacial compatibility for electronic packaging and thermal interface materials. In October 2025, the company also introduced spherical silica (SiO₂) powder with high sphericity, surface smoothness, and batch consistency for electronics, coatings, and composites applications.
