A lubricant for the topical application to objects that will contact various forms of water, e.g., liquid, snow, ice, or mixtures thereof, to reduce friction and thereby increase speed, glide and maneuverability. The lubricant consists essentially of hexagonal boron nitride and a binder of single or mixed oxides or organics, the boron nitride content (after drying) being from about 36 wt. % to about 99 wt. %. Binders of particular interest are water-based colloidal aluminum oxide and colloidal silicon dioxide. This lubricant is suitable for topical applications in a thin layer to various sports objects, such as skis, snowboards, ice skates, snowmobiles, toboggans, sleds, boats, etc., where reduced friction, and thus higher speed, glide and maneuverability is desired. Although a solid stick form (by drying or pressure-less sintering) is preferred, the lubricant can be in the form of a paste or a powder. Further, this lubricant can be incorporated into waxes of the type previously used for friction reduction to obtain the benefit of both.
