In some embodiments, a compound has the formula (I) where: Rand Rare alkyl or, together with the carbon atom to which they are attached, cycloalkyl; R, Rand Rare H or alkyl (formula II); Ris alkyl or where: Rand Rare H, alkyl or, together with the carbon atom to which they are attached, cycloalkyl; Ris H or alkyl; X is alkylene or is absent; and p is 0, 1, 2 or 3; and m and n are 0, 1, 2 or 3 provided that m is 0 when Rand Rare H. The compound is suitable for use as a base stock which provides low volatility for a given viscosity profile. The compound may be used in a lubricant composition for an internal combustion engine.

The process of the present invention begins with a source of silicon and silicon carbide from wafer production. The silicon/silicon carbide waste material is dewatered as need be and passed to a mixer where the waste material is agglomerated. A binder is applied to the waste material either during agglomeration or during pelletizing. A variety of organic binders may be used such as polyvinyl alcohol, molasses, sodium silicate and polyethylene glycol; however, the preferred binder is a lignosulsulfonate. The amount of binder used will depend upon the particular binder and the feed material used. The silicon/silicon carbide-containing waste material is pelletized. The invention also provided silicon/silicon carbide-containing pellets that may be used as reduction material in smelting furnaces for the production of metals and alloys.
