Abstract
The invention relates to high-purity titanium boride (TiB) ceramic powder with a face-centered cubic structure and a preparation method thereof. The TiB ceramic powder is a compound consisting of the following chemical components: 40 to 60 percent of titanium (Ti) element and 40 to 60 percent of boron (B) element, wherein the chemical formula of the compound is TiB and the atom proportion is as same as the chemical components; and at the temperature below the melting point, the TiB ceramic powder is in a solid powder state and has a crystal structure, the atoms are arranged in a face-centeredcubic lattice mode, namely the TiB crystal consists of face-centered cubic unit cells, and the face-centered cubic unit cells are characterized in that: when an atom performs face-centered translation, atoms with the identical ambient environment can be obtained. The preparation method of the TiB ceramic powder comprises five steps of pressing green compacts, preparing a solid penetrating agent, placing the green compacts into boxes, sintering and preparing the powder. The high-purity TiB ceramic powder with the face-centered cubic structure and the preparation method thereof have the advantages of simple process, low cost, easily-controlled quality and suitability for industrialized production.
Description
technical field [0001] The invention relates to a ceramic powder material and a preparation method thereof, belonging to the field of engineering materials. Background technique [0002] Ceramic is an important and special engineering material, which has the characteristics of high temperature resistance, corrosion resistance, wear resistance and special functions, and is a material that must be used in special occasions. Ceramics are compounds formed of metal elements and non-metal elements. The compound formed by oxygen and metal is usually called oxide ceramics, among which Al 2 o 3 and CeO 2 Wait. There is also a class of ceramics made of metal and non-oxygen elements, such as SiC, SiN, MoSi 2 , TiN and TiC, etc., they are attributed to non-oxide ceramics. This type of ceramics exhibits very good performance in terms of high temperature resistance, corrosion resistance and wear resistance. Among them, the strength of silicon nitride SiN can reach 700MP; the hardne...
