Abstract: Small particle compositions including nanoparticle compositions are provided. The particle compositions, in some cases, are characterized by having an extremely small average particle size (e.g., 150 nanometers or less). The small particles may comprise a semiconductor material and/or a light-emitting material. In some embodiments, the particles may be in the form a preferred shape including platelets, amongst others. The small particle compositions may be produced in a milling process. In some embodiments, the milling process uses preferred types of grinding media to form milled particles having desired characteristics (e.g., particle size, shape). The small (or nano) particle compositions may be used in a variety of different applications including light-emitting applications. In certain applications, it may be desirable to form thin films from the small particle compositions.

Abstract: A polishing compound is disclosed which is relatively high purity silicon nitride, the silicon nitride comprising particles having equiaxial crystals, the particle size being from about 0.03 to about 5 microns.

Abstract: A wire bonding tool is disclosed which comprises a metal or cermet stem and a silicon nitride containing tip. The tip is made of a silicon nitride containing composite which is electrically conducting. One end of the tip is fixedly mounted to one end of the stem.

Abstract: An abrasive frit is disclosed comprising particles of a silicon nitride based material. The particles have essentially sharp edges and a particle size within the range of from about 0.5 to about 150 microns. An abrasive frit is disclosed as described above except that the edges of the particles are essentially smooth. A method is disclosed for producing a abrasive frit of silicon nitride based material. The method involves forming a body of silicon nitride based material, firing the body at a sufficient temperature for a sufficient time to form a relatively low density body which is then crushed to form fragmented material a portion of which comprises essentially sharp edged particles in the above given size range, followed by separating the particles from the balance of the fragmented material. At this point the sharp edged particles can be either polished to produce essentially smooth edges particles or left as is.

Abstract: In a process for producing a carbide grade powder mixture for making a cemented metal carbide, a mixture of metal carbide particles and wax is formed at a temperature above the melting point of the wax. The wax includes less than about 2 percent by weight of a wetting agent for reducing the surface tension of the wax when in water. The blended mixture including metal binder particles is milled with a liquid milling medium comprising water to substantially uniformly disperse the metal binder particles and to produce a slurry. The slurry is dried to remove the milling medium and produce a powder comprising particles of metal carbide, metal binder and wax.
