DEFINITION

Classification: 501/96.1

Boride, silicide, nitride, oxynitride, carbonitride, or oxycarbonitride containing:

(under subclass 94) Compositions comprising at least one compound which is a boride, silicide, nitride, oxynitride, carbonitride, or oxycarbonitride.

(1) Note. A silicide is a binary compound of a metal or other more positive element with silicon (e.g., Mg2Si, etc.).

(2) Note. A boride is a binary compound of boron with a more positive element (e.g., Mg3B2, Si3B4, etc.).

(3) Note. A nitride is a binary compound of nitrogen with a metal (e.g., Mg3N2, etc.).

(4) Note. An oxynitride is a ternary or quaternary inorganic

compound of nitrogen, oxygen, and a more positive element of the type GAOBNC or GAJBOCND wherein G and J are the more positive elements, and A, B, C, and D are greater than zero.

(5) Note. A carbonitride is a ternary inorganic compound of nitrogen, carbon, and a more positive element of the type GACBNC wherein G is the more positive element, and A, B, and C are greater than zero.

(6) Note. An oxycarbonitride is a quaternary inorganic compound of oxygen, carbon, nitrogen, and a more positive element of the type GA[end subscrpt]OBCC[end subscrpt]ND, wherein G is the more positive element, and A, B, C, and D are greater than zero.
