What Is The Difference Between Alpha SiC And Beta SiC In
Mar 11 2019 · Cubic silicon carbide also known as Beta sic is a cubic crystal system. The Beta sic hardness is 9.25--9.6 which is close to the diamond 10 and has a better finish than diamond. Beta sic is one of the hardest high-performance materials after steel. Its ultra-high hardness and density make it ideal for parts subject to high wear and sliding wear.

Fabrication of a Monolithic Implantable Neural Interface
Crystalline silicon carbide (SiC) is a semiconductor with a short bond length that gives it high physical resilience and chemical inertness. One of the important properties of SiC is that it displays polymorphism which results in numerous single-crystal forms with the principal being hexagonal (i.e. 4H- and 6H-SiC) and cubic (i.e. 3C-SiC).
