Carbon-Ceramic Molten Silicon Infiltration Furnace

Carbon-Ceramic Molten Silicon Infiltration Furnace

Equipment Core: Designed for silicon infiltration into carbon-ceramic matrices under high temperatures (up to 2300°C), significantly enhancing material hardness and wear resistance. Technical Advantage: Features exceptional pressure differential control capability, thoroughly eliminating backflow contamination from secondary silicon vapor generated by heating elements and insulation materials. Multi-Functional Adaptability: Supports customization of circular or square furnace chambers, suitable for complex infiltration processes involving various gas mixtures such as MTS, Ar, H?, natural gas, and others.

Overview

Carbon-ceramic silicon infiltration is an advanced ceramic material processing method. The molten silicon infiltration furnace manufactured by Yuanhang Industrial Furnace operates by placing the carbon-ceramic matrix in a silicon-rich environment and heating it to ultra-high temperatures. Utilizing capillary forces, silicon elements diffuse into the pores of the ceramic matrix. After solidification and crystallization, this process forms a carbon-ceramic composite material characterized by extremely high hardness, wear resistance, and corrosion resistance.
