The present invention relates to compositions and methods for forming a bit body for an earth-boring bit. The bit body may comprise hard particles, wherein the hard particles comprise at least one carbide, nitride, boride, and oxide and solid solutions thereof, and a binder binding together the hard particles. The binder may comprise at least one metal selected from cobalt, nickel, and iron, and, optionally, at least one melting point reducing constituent selected from a transition metal carbide in the range of 30 to 60 weight percent, boron up to 10 weight percent, silicon up to 20 weight percent, chromium up to 20 weight percent, and manganese up to 25 weight percent, wherein the weight percentages are based on the total weight of the binder. In addition, the hard particles may comprise at least one of (i) cast carbide (WC+W2C) particles, (ii) transition metal carbide particles selected from the carbides of titanium, chromium, vanadium, zirconium, hafnium, tantalum, molybdenum, niobium, and tungsten, and (iii) sintered cemented carbide particles.

A composite contains substrate fibers, and an activated organic coating, on the substrate fibers. The activated organic coating is formed at a low temperature, making possible the use of substrate fibers have a softening or decomposition temperature of at most 500° C.

The present invention relates to a quick-disintegrating tablet in the buccal cavity comprising a drug, a diluent, and a saccharide with a relatively lower melting point than the drug and the diluent, which is obtained by uniformly mixing the saccharide with a low melting point in the tablet so that a bridge will be formed between said drug and / or said diluent particles by the product of melting and then solidification of this saccharide with a low melting point. Moreover, the present invention relates to a method of manufacturing a quick-disintegrating tablet in the buccal cavity comprising a drug, a diluent and a saccharide with a relatively lower melting point than the drug and the diluent, which comprises (a) the process whereby tablet starting materials including a drug, a diluent, and a saccharide with a relatively lower melting point than the drug and the diluent are molded under the low pressure necessary for retaining the shape of a tablet, (b) the process whereby the molded product obtained in process (a) is heated to at least the temperature at which this saccharide with a low melting point will melt, and (c) the process whereby the molded product obtained in process (b) is cooled to at least the temperature at which the molten saccharide with a low melting point solidifies. The present invention presents a quick-disintegrating tablet in the buccal cavity that can be used for practical purposes in that it has almost the same properties as conventional oral pharmaceutical tablets, that is, it has sufficient tablet strength that it can be used with automatic unit dosing machines, and it is produced by conventional tableting machines, and a manufacturing method thereof. Moreover, the present invention presents a quick-disintegrating tablet in the buccal cavity which, in comparison to conventional quick-disintegrating tablets in the buccal cavity, has increased tablet strength and an improved friability without prolonging the disintegration time in the buccal cavity, and a manufacturing method thereof.

The invention relates to a monocrystal-like lithium battery ternary cathode material and a preparation method thereof. The chemical formula of the cathode material is LiNi(1-x-y-z)CoxMnyMzO2, wherein x is larger than 0 and smaller than or equal to 0.65, y is larger than 0 and smaller than or equal to 0.3, z is larger than or equal to 0 and smaller than or equal to 0.05, and M is one or more of Mg, Ca, Ti, Zn, Cr, Fe, Zr, Co, Cu and Ru. The preparation method of the cathode material comprises the following steps of 1 precursor synthesizing; 2 material mixing, wherein a fluxing agent is added in the material mixing process; 3 sintering and the like. According to the method, the melting point of the material is lowered by adding the fluxing agent, therefore, precursors and lithium salts are in a molten environment, dispersion of metal ions is accelerated, and crystal grains start to grow and development at low temperature, break limitation of precursor aggregates after growing to a certain degree to be dispersed into monocrystal grains and finally grow into the cathode material with the monocrystal morphology; the sintering frequency and the sintering time in the existing monocrystal material synthesizing process are decreased, and then the production cost is reduced.
