Abstract: A masterbatch composition comprises a composite of a polymer resin material and boron nitride. The masterbatch composition can be in the form of a powder or particles. The masterbatch composition can impart improved properties such as wear resistance, thermal conductivity, compressibility, etc., to a composition or article formed from the masterbatch composition. In one embodiment, the masterbatch composition can be used to form a brake pad composition and provides a brake pad with improved properties compared to a composition formed by dry blending the separate boron nitride and resin materials.

Abstract: A method for growing a crystalline composition, the first crystalline composition may include gallium and nitrogen. The crystalline composition may have an infrared absorption peak at about 3175 cm−1, with an absorbance per unit thickness of greater than about 0.01 cm−1. In one embodiment, the composition may have an amount of oxygen present in a concentration of less than about 3×1018 per cubic centimeter, and may be free of two-dimensional planar boundary defects in a determined volume of the first crystalline composition.
