Melting and Refining Tantalum Pellets

Mechanical force chemical processing equipment includes some equipment with crushing effect, such as vibration mill, ball mill, airflow crusher, planetary mill, and other equipment with crushing effect. Gas-phase processing equipment includes a fluidized bed, airflow turbulent particle dispersion, modification equipment, etc. The high-energy radiation mechanical method is in the friction, grinding, impact, vibration, and high-speed mixing and other mechanical forces, small particles and large particles will be a solid-phase reaction or mechanical mosaic and other effects so that the small particles covered in large particle surface. For example, Hybridization, a high-speed airflow impact type powder surface modification equipment developed and produced by Nara Machinery Works in Japan, is used to carry out the compounding modification treatment of inorganic particles/polymers, metals/metals, inorganic particles/metals, and other types, and many functional particle materials are obtained, which is a particle compounding modification method capable of industrial processing at present. Processing equipment: including plasma type, laser beam type, electron beam type, and other equipment. 

Particle surfaces modification treatment mainly relies on the adsorption of the modifier on the particle surface to achieve, therefore, the nature of the modifier plays a decisive role in the surface properties of the modified particles. At present, the commonly used modifiers are coupling agents (titanate coupling agent, silane coupling agent, aluminate coupling agent), surfactants, organic oligomers, silicones, etc., of which coupling agents is currently the most commonly used class of inorganic particles modifiers. The mechanism of action of coupling agent and particle surface includes physical adsorption theory, reversible hydrolysis equilibrium theory, chemical bonding theory, etc. The mechanism of action of coupling agent and organic matrix includes chemical bonding theory, infiltration effect theory, interfacial layer theory (deformable layer theory and bound layer theory), etc.

At present, the evaluation methods of particle surface modification effect is not yet perfect and standardized. The evaluation methods of surface modification effect can be generally divided into direct evaluation method and indirect evaluation method. The methods to realize the compounding modification of micro/nanoparticles is physical methods, mechanical methods, chemical methods, etc. The physical method is to deposit a nanoparticle film on the particle surface by the action of physical deposition. Such as the use of magnetron sputtering coating or vacuum vapor deposition method  of  the micro-particle surface deposition of gold, silver, copper, tantalum, cobalt, nickel, and other metal particles film. The chemical method  are the method of depositing a layer of particle film on the surface of particles by a certain chemical reaction. The mechanical method is Under the action of mechanical forces such as friction, grinding, impact, vibration, and high-speed stirring, small particles and large particles will undergo solid-phase reactions or mechanical mosaic and other effects so that small particles are coated into the surface of large particles.
