Products Description

Reaction bonded silicon carbide, often abbreviated as RBSC or RBSiC, is a high-performance ceramic material prepared through a unique chemical reaction process. The core process involves placing a porous carbon body (typically made of a mixture of silicon carbide and carbon) in a molten silicon or silicon vapor environment. At high temperatures (usually above 1400°C), silicon reacts in situ with the carbon in the body to form a new silicon carbide phase that is tightly bonded to the original silicon carbide framework. Unreacted silicon fills the remaining pores, ultimately resulting in a dense composite material composed of the original silicon carbide, reaction-formed silicon carbide, and a small amount of free silicon (typically 5-15%).

Main performance ：

Outstanding high-temperature performance: It can maintain high strength and hardness even at temperatures as high as 1350°C, and its oxidation resistance is superior to that of many metals and ceramics.
Outstanding thermal performance: It features a high thermal conductivity (second only to pure silicon carbide ceramics), excellent thermal shock stability (resistant to rapid temperature changes), and a relatively low coefficient of thermal expansion.
Outstanding mechanical properties: high hardness, excellent wear resistance, high mechanical strength, especially with outstanding bending strength.
Good chemical stability: resistant to erosion by various acids, alkalis, molten salts and metal melts (except for strong alkalis and molten oxidants).
Machinability and near-net-shape forming: The green body is easy to be machined into complex shapes, and the dimensional change after reaction sintering is extremely small (<1%), enabling near-net-shape forming and reducing the subsequent processing costs.
Relatively low cost: Compared with fully sintered atmospheric pressure sintered silicon carbide or pressureless sintered silicon carbide, it has a lower sintering temperature, shorter sintering time, and more competitive manufacturing costs.

Main application:

High-temperature kiln furniture and refractory materials: Widely used in the ceramic, powder metallurgy, glass and other industries, they are used as push plates, roof plates, beams, roller rods, etc. They have a long service life and significant energy-saving effects.
Wear-resistant and sealing components: Used for manufacturing mechanical seal rings, sliding bearings, nozzles, liners, etc., suitable for harsh abrasive and corrosive environments.
Semiconductor manufacturing equipment: As a key consumable, it is used to make wafer epitaxial trays, diffusion furnace paddles, etching equipment components, etc., due to its high purity, high-temperature resistance, and resistance to plasma erosion.
Chemical and metallurgical industries: Used for manufacturing heat exchangers, pump and valve components, crucibles, aluminum liquid flow tubes, etc., resistant to corrosion by molten metals and chemicals.
In the field of new energy and environmental protection: nozzles and heat exchangers for flue gas purification systems; thermal field components (such as heaters and crucibles) for polycrystalline silicon casting furnaces in the solar photovoltaic industry.
Aerospace and defense: Used for manufacturing lightweight and high-performance mirror blanks, optical structural components, and certain engine parts.
Lightweighting and braking systems: As one of the materials for high-performance brake discs (particularly in racing and aviation), it has the advantages of high-temperature resistance and thermal fade resistance.
