Preparation method of titanium diboride raw material

Using titanium and boron oxides as raw materials and carbon black as a reducing agent, a long-term high-temperature carbon reduction process is conducted in a carbon tube furnace. The purity of the synthesized titanium diboride powder depends on the purity of the raw material powder. This method is a process that is widely used in industrial production. Still, its disadvantages lie in the large volume of titanium diboride powder particles obtained and the high content of impurities. Self-propagating high-temperature synthesis method: This method generally involves pressing the raw material mixture to be reacted into a block shape and then igniting the reaction at one end of the block. The immense heat generated by the response causes the adjacent materials to react, resulting in a combustion wave that propagates at speed v. Finally, as the combustion wave advances, the raw material mixture is converted into the final product. Due to the self-purification effect of the self-propagating high-temperature synthesis process and the high purity of the product, the obtained powder is easy to sinter further and consumes less external energy. When combined with other unique technical means, dense titanium diboride materials can be directly prepared. Mechanochemical reaction method: This method involves placing the reactant powder in a high-energy ball mill, and the powder undergoes a repeated transformation process from deformation to fragmentation under compression and shearing of the grinding ball. The severe friction and collision of the ball milling medium convert mechanical energy into chemical energy, thereby synthesizing the required reactants. Compared to the previous two methods for preparing titanium diboride, the mechanochemical reaction method has the advantages of low synthesis temperature, comprehensive source of raw materials, and low cost.
