Plaques céramiques en carbure de silicium de forme irrégulière

Plaques céramiques en carbure de silicium de forme irrégulière are high-performance ceramic components with specific non-standard geometric shapes, which are prepared mainly from high-purity silicon carbide (SiC) through advanced forming processes (such as injection molding, gel injection molding, isostatic pressing) and high-temperature sintering. It is not a simple plate or disc, but is custom-made into various complex shapes according to the customer’s equipment structure, fluid path or installation requirements, such as turbines, crucibles, nozzles, guide rails, sealing rings, special-shaped liners, etc.
Silicon carbide material itself is hailed as the “third-generation semiconductor material” and the “teeth of industry”, with extremely outstanding comprehensive performance. Based on this, our irregular-shaped silicon carbide ceramic plates, through precise size and shape control, perfectly combine the outstanding performance of the material with specific engineering applications, achieving the unity of “function and form”.

Core features and problems solved:
Ultimate wear resistance, solving the problems of rapid equipment wear and frequent shutdowns
The hardness of silicon carbide is second only to that of diamond and cubic boron nitride, and its wear resistance far exceeds that of metals and other structural ceramics. Under conditions of severe wear and tear, it can extend the service life of key components of the equipment several times or even dozens of times, greatly reducing the downtime for replacement and lowering maintenance costs.
Outstanding high-temperature resistance and thermal shock resistance, solving the problems of high-temperature deformation and cracking
The product can be used for a long time at a high temperature of 1600°C, and the short-term usage temperature is even higher. Meanwhile, it has a small coefficient of thermal expansion and a high thermal conductivity, which endows it with excellent thermal shock resistance (resistance to sudden temperature changes). It can effectively cope with environments with sudden temperature changes, avoiding cracking due to thermal stress like ordinary ceramics, and solving the core pain point of easy deformation and failure of materials in high-temperature equipment.
Outstanding chemical corrosion resistance, addressing the dual challenges of coexistence of corrosion and wear:
Silicon carbide has extremely high chemical inertness and can resist the erosion of various strong acids (such as sulfuric acid, hydrochloric acid, nitric acid), strong alkalis and molten metals. In industries such as chemical engineering and metallurgy, when components are simultaneously exposed to chemical corrosion and mechanical wear, irregular-shaped silicon carbide ceramic plates are an almost perfect solution.
High strength, low density, achieving lightweight and high stability
Its compressive strength and flexural strength are extremely high, but its density is only one third of that of steel. This means that while achieving the same or even higher structural strength, it can effectively reduce the load on the equipment, and is particularly suitable for high-speed rotating parts or weight-sensitive application scenarios.
