In the field of advanced ceramic materials, Engineering Ceramice, through in-depth research and development and industrial application of silicon carbide (SiC) ceramics, has formed a complete product line covering high-temperature structural components, wear-resistant parts, semiconductor equipment and other fields. The differentiated advantages of the company's silicon carbide ceramic products stem from the deep integration of the physical and chemical properties of the material itself and engineering technology. The following is an analysis of the core of its market competitiveness from four dimensions.
Adaptability to Extreme Environments
The crystal structure of silicon carbide ceramics endows them with excellent thermal stability, and their coefficient of thermal expansion is only one-third of that of alumina ceramics. This makes it an ideal material for ultra-high-temperature scenarios such as the combustion chambers of aero engines and control rods of nuclear reactors. Engineering Ceramice optimized the grain boundary structure through the gas phase permeation (CVI) process, increasing the thermal shock resistance of the product to 200 times (1000℃ water quenching cycle), which is 40% higher than that of the traditional process.
Breakthrough in multi-dimensional mechanical properties
The company adopts nano-toughening technology to add second-phase titanium carbide particles to the silicon carbide matrix, forming a unique "core-shell" microstructure. This design enables the material to maintain an extremely high flexural strength while enhancing its fracture toughness.
Functionalized Surface Engineering
Through the chemical vapor deposition (CVD) process, Engineering Ceramice developed a gradient functional coating system. The bottom layer is a dense silicon carbide transition layer, the middle layer adopts boron nitride buffer phase, and the surface layer is deposited with diamond-like carbon (DLC) film. This structural design reduces the wear rate of the product in corrosive media to 0.002mm³/N·m, while keeping the coefficient of friction within the range of 0.08 to 0.12, meeting the strict working conditions of polycrystalline silicon pulling furnaces in the photovoltaic industry.
Full-process quality control
From the control of raw material purity (oxygen content of SiC powder ≤0.3wt%) to the optimization of sintering process (pressure-assisted sintering temperature accurate to ±5℃), Engineering Ceramice has established a digital quality traceability system covering 12 key processes. Internal defect three-dimensional visualization detection is achieved through X-ray tomography (XCT) technology to ensure that the product porosity is less than 0.1% and the dimensional tolerance is controlled within ±0.02mm, meeting the international standards for precision ceramics used in semiconductor equipment.
Engineering Ceramice has continuously invested in the construction of the metamaterial design platform and has obtained 17 patent authorizations related to silicon carbide ceramics. The company is promoting the application of 4D printing technology in the manufacturing of complex structural components. Through a spatio-temporal controllable sintering shrinkage compensation algorithm, it breaks through the geometric limitations of traditional forming processes. This deep coupling of technological innovation and industrial demands has enabled Engineering Ceramice to maintain an average annual market growth rate of 35% in strategic emerging fields such as new energy and semiconductor equipment.
