Electronic Structure and Chemical Bonding of Nickel

The electronic structure, magnetic states, and chemical bonding of a nickel impurity in cubic silicon carbide (β-SiC) were studied by the ab initioself-consistent discrete variation method depending on the position of the impurity in the crystal. The interstitial (Ni(i)) and substitution (Ni(s)) positions were considered and more complex (paired) Ni(i)–Si vacancy and Ni(s)–Si(i) types of

Technology & Materials - Paxis Ceramics

Reaction bonded silicon carbide (RBSC) is produced from a finely divided mixture of silicon carbide and carbon. The silicon reacts with the carbon to form additional silicon carbide, bonding the particles together. Silicon also fills the residual open pores. RBSC undergoes minimal dimensional change during sintering (less than 0.1%).

Tetrahedra of Structure, Bonding & Material Type

Tetrahedra of Structure, Bonding & Material Type. The van Arkel-Ketelaar triangle, as discussed on the previous page of this web book, recognises that the chemical elements & binary compounds exhibit three extreme types of bonding: Metallic, Ionic & Covalent. But this can not the whole story because covalently bonded materials are seen to take two extreme forms.

Covalent Crystals | Introduction to Chemistry

Silicon carbide (SiC) is also known as carborundum. Its structure is very much like that of diamond, with every other carbon replaced by silicon. Silicon carbide exists in about 250 crystalline forms. It is used mostly in its synthetic form because it is extremely rare in nature.
