Panadyne Inc.: Silicon Carbide

Silicon Carbide, sometimes mistakenly referred to by the trade name Carborundum, is used due to its properties of high hardness (Mohs hardness 9), wear resistance, its chemical inertness, high thermal conductivity, abrasion resistance, low coefficient of thermal expansion, thermal shock resistance, and strength at high temperature ranges.

Breaking the icosahedra in boron carbide

Oct 25, 2016For boron carbide, the relative bond strength between the atoms in the icosahedra and chains is still being debated, but the icosahedra are generally thought to be very strong and stable because of their near-spherical shape and the highly delocalized fullerene-like intraicosahedral sp 2 bonds (3, 7 ⇓ ⇓ –10).As a result of its high hardness, boron carbide is an excellent candidate for

Structure and bonding in boron carbide: The invincibility

Boron carbide, usually described as B 4 C, has the mysterious ability to accommodate a large variation in carbon composition (to as much as B 10 C) without undergoing a basic structural change. We systematically explore how the bonding varies with carbon concentration in this structure and the origin of the fundamental electron deficiency of the phase.

Boron Carbide with Reliable Quality and Competitive B4C

Boron carbide is a semiconductor, with electronic properties dominated by hopping-type transport.[8] The energy band gap depends on composition as well as the degree of order. The band gap is estimated at 2.09 eV, with multiple mid-bandgap states which complicate the photoluminescence spectrum.[8] The material is typically p-type.
