Silicon Carbide SiC Material Properties - Accuratus
Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800 C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C. The high thermal conductivity coupled with low thermal expansion and high strength give this material exceptional thermal shock resistant qualities.

Silicon carbide Powder Highly Pure Less Price Fast Delivery
Silicon Carbide Powder: The ability of Silicon Carbide to withstand very high temperatures without breaking or distorting is used in the manufacture of ceramic brake discs for sports cars. It is also used in bulletproof vests as an armor material and as a seal ring material for pump shaft sealing where it frequently runs at high speed in contact with a similar silicon carbide seal.
Crystal structure of boron-rich metal borides - Wikipedia
Metals, and specifically rare-earth elements, form numerous chemical complexes with boron.Their crystal structure and chemical bonding depend strongly on the metal element M and on its atomic ratio to boron. When B/M ratio exceeds 12, boron atoms form B 12 icosahedra which are linked into a three-dimensional boron framework, and the metal atoms reside in the voids of this framework.
