On the afternoon of September 17, 2021, China's Shenzhou 12 spacecraft returned to Earth carrying three astronauts.
In this mission, high-performance silicon carbide ceramic components developed by China's leading manufacturer of silicon carbide ceramic precision components: NBFE Ceramic Technology Corporation were used in key systems of deep space exploration equipment.
The large size silicon carbide ceramic sealing ring produced by NBFE is the core component of the large radar cooling system.
NBFE has been focusing on the field of silicon carbide ceramic materials for more than ten years, has participated in the formulation of more than ten national and industry standards, and obtained 28 invention patents. The company has built a national demonstration academician workstation, a provincial postdoctoral workstation, a provincial engineering ceramic high-tech R&D center and other platforms.
In recent years, under the leadership of major national projects undertaken by China Aerospace Science and Technology Group and China Electronics Technology Group, NBFE has devoted itself to the development of a variety of high-performance silicon carbide ceramic components, and has been successfully selected into the list of China's silicon carbide ceramic invisible champion enterprises.
In addition to large-scale radars for aerospace, NBFE has also provided silicon carbide ceramic bearings for China's nuclear power plant "Hualong No. 1", and silicon carbide ceramic mechanical seal systems for deep-sea drilling platforms and shale gas development.
