Nitrides - Ceramic Materials - H.C. Starck

They are usually characterized by a high degree of thermal stability and exceptional chemical stability. In addition to saline and metallic nitrides, there are also covalent nitrides, such as aluminum nitride. H.C. Starck provides a wide range of nitrides, including high-purity silicon nitride with purity of 99.995 percent.

Boron - ScienceDirect

The uses in the glass and ceramics industries reflect the diagonal relation between boron and silicon and the similarity of vitreous borate and silie networks (pp. 203, 206 and 347).In the UK and continental Europe (but not in the USA or Japan) sodium perborate is a major constituent of washing powders since it hydrolyses to H 2 O 2 and acts as a bleaching agent in very hot water (∼90°C

Physics and Astronomy Calendar - Physics at Minnesota

Via the development and appliion of rigorous numerical models, we were able, for the first time in over a decade of research on this system, to quantitatively describe data on the engulfment of SiC (silicon carbide) particles during the growth of crystalline silicon.

Boranes are similar to silanes, boron carbide is similar to silicon carbide, and so forth. The special similarity of the modifiions of the nitride BN with graphite or diamond is of interest. This phenomenon is associated with the fact that atoms of B and N together imitate two atoms of C in electron configuration.

Valency: The coining capacity of an element is known as valency. The coining capacity of the atoms to form molecules either with same or different elements is defined as valency. Atom contains less than four electrons in its outermost shell; the valency of an atom is equal to the nuer of electrons present in the valence shell. Examples:

Gallium - Element information, properties and uses

Gallium arsenide has a similar structure to silicon and is a useful silicon substitute for the electronics industry. It is an important component of many semiconductors. It is also used in red LEDs (light emitting diodes) because of its ability to convert electricity to light. Solar panels on the Mars Exploration Rover contained gallium arsenide.
