Silicon carbide is a semiconductor which possesses extreme resistance to corrosive chemistries, experiences only limited oxidation, and has demonstrated no appreciable toxicity [65,66,67,68]. We have demonstrated that hexagonal silicon carbide junction isolation electrode devices have a much higher forward bias turn-on potential than Si (2.3 V vs. 0.7 V).

Researchers Develop Formula That Makes Body Armor …

12/4/2019· Boron carbide can be fairly easily produced in bulk, which is not the case with cubic boron nitride. Boron carbide is a far superior material for body armor because it is lighter and harder than other protective materials, such as silicon carbide.
