Thanks to its high strength, high hardness, high thermal conductivity, and near-inert chemical stability, silicon carbide ceramic has become the ideal material for high-temperature semiconductor processes and highly corrosive chemical environments.
Extended Service Life: The service life of furnace tubes and wafer boats is 5 to 10 times longer than that of quartz products, and heat exchange equipment can last for over 10 years.
Ultra-high purity: Semiconductor-grade products have substrate impurities of <300 ppm, and surface impurities of <5 ppm after coating, eliminating wafer contamination.
High Thermal Conductivity: Thermal conductivity ranges from 120 to 270 W/(m·K), approximately five times that of stainless steel, resulting in significantly superior heat transfer efficiency.
Low Maintenance Costs: With excellent wear and corrosion resistance, the modular design facilitates easy cleaning and inspection, substantially reducing downtime and maintenance-related losses.
Thanks to their high-temperature resistance, corrosion resistance, high thermal conductivity, and chemical stability, silicon carbide ceramics are widely used in cutting-edge fields such as highly corrosive heat exchange in chemical processing, high-temperature semiconductor manufacturing processes, third-generation semiconductors, and new energy. Jingfu New Materials’ core products include silicon carbide heat exchange blocks, heat exchange tubes, vertical semiconductor crystal boats, and furnace tubes, primarily serving the following four major sectors:
Used for heating and cooling highly corrosive media such as sulfuric acid and hydrofluoric acid in industries including chlor-alkali, hydrometallurgy, and fine chemicals, these systems are an ideal alternative to graphite and precious metal heat exchangers.
Covering equipment such as oxidation and diffusion furnaces, LPCVD systems, and annealing furnaces, silicon carbide furnace tubes serve as core chamber components to provide a pure, high-temperature environment, while vertical silicon carbide boats stably support wafers throughout the heat treatment process.
Used in thin-film deposition processes such as CVD and ALD, vertical silicon carbide wafer boats provide high-purity, high-temperature-resistant wafer support within the reaction chamber, ensuring film uniformity and yield.
Used in high-temperature, highly corrosive exhaust gas treatment systems for the semiconductor and chemical industries, silicon carbide furnace tubes and heat exchanger tubes can withstand long-term exposure to acidic exhaust gas erosion and corrosion, ensuring safe and stable system operation.

Jingfu New Materials is a professional silicon carbide ceramic manufacturer with its production facility located on Lianzhong Road, Yizheng Development Zone, Yangzhou, Jiangsu Province.
Our core product lines include SiC furnace tubes, semiconductor SiC vertical wafer boats, SiC heat exchanger tubes, and SiC heat exchanger blocks.
These products widely serve high-temperature processes and highly corrosive heat exchange applications across semiconductor, photovoltaic, chemical, pharmaceutical, and metallurgical industries.
We offer multiple material grades including reaction-bonded silicon carbide (RBSC) and solid-state sintered silicon carbide (SSiC) to meet diverse operating conditions.
SiC furnace tubes far surpass traditional quartz tubes in high-temperature strength, thermal shock resistance, and service life.
While quartz tubes are prone to devitrification and softening at elevated temperatures, SiC furnace tubes — with their high thermal conductivity and low thermal expansion coefficient — remain deformation-free and sag-free over long-term use.
The service life of SiC furnace tubes can be several times that of quartz, significantly reducing replacement frequency and total cost of ownership.
Moreover, SiC furnace tubes offer high purity and excellent chemical stability, preventing impurity contamination during high-temperature processes.
As a result, they are increasingly replacing quartz tubes in semiconductor oxidation diffusion furnaces, LPCVD, and annealing furnaces.
Thanks to their nearly inert chemical stability, SiC heat exchanger tubes and blocks withstand strong acids including hydrofluoric acid, nitric acid, hydrochloric acid, and sulfuric acid, as well as mixed acids.
They also resist strong alkalis such as sodium hydroxide and most organic solvents.
Under extreme corrosive conditions such as 98% concentrated sulfuric acid and HF-containing mixed acids, the annual corrosion rate is below 0.005mm.
This makes SiC heat exchange products a high-performance alternative to graphite, stainless steel, tantalum, Hastelloy, and fluoroplastic heat exchangers.
These products have been widely and reliably applied across chlor-alkali, hydrometallurgy, and fine chemical industries.
Yes, Jingfu New Materials provides full-chain customization services from powder to finished product, backed by a technical team of over 30 professionals.
Customization scope includes dimensions (from small precision wafer boats to large furnace tubes) and shapes (standard round tubes, square slots, and complex irregular parts).
We also offer material grade customization (RBSC/SSiC/RSiC) and functional coating solutions (high-temperature oxidation-resistant coatings, high-purity CVD SiC coatings, etc.).
Additionally, we provide matching solutions tailored to specific operating conditions, ensuring that products are highly compatible with actual use environments.
Customers can provide drawings for precise reproduction, or collaborate with us to develop entirely new designs from scratch.
Jingfu’s semiconductor-grade SiC furnace tubes and wafer boats are manufactured from high-purity SiC raw materials, with substrate impurity content below 30 PPM.
For customers with more stringent cleanliness requirements, we can apply a CVD SiC coating to the product surface.
After coating, surface impurity content can be controlled to below 5 PPM, eliminating the risk of metal ion leaching and wafer contamination during high-temperature processes.
This purity level fully meets the ultra-high purity demands of advanced semiconductor manufacturing.
With their exceptionally high thermal conductivity, SiC heat exchanger blocks require a much smaller heat exchange area than traditional glass-lined and graphite heat exchangers under equivalent heat loads.
This results in a more compact overall design, significantly saving valuable installation space on the production floor.
SiC heat exchangers typically feature a removable modular design, allowing individual blocks to be detached for easy routine inspection and cleaning on both the tube and shell sides.
Their superior corrosion and wear resistance ensure long-term leak-free and blockage-free operation, substantially reducing unplanned downtime and repair frequency.
Therefore, SiC heat exchanger blocks not only save initial installation space but also greatly reduce total lifecycle maintenance costs, making them a key component for enhancing the overall efficiency of chemical production lines.
