The invention provides a Potassium Fluotitanate (KTIF6) manufacture process. The Potassium Fluotitanate (KTIF6) manufacture process includes steps: A. providing titanium ferrum powder to a reaction furnace and adding HF and peroxide solution to react with the titanium ferrum powder sufficiently to manufacture HTiF, B. filtrating the sufficiently mixed solution of step A and adding it to another reaction furnace, and then after the HTiFcools off, adding Potassium Chloride (KCl) solution to react with the mixed solution to manufacture Potassium Fluotitanate (KTiF); C. adding KCOsolution to the remaining solution of step B and react with the remaining solution and controlling the pH value, the element Fe is recycled by a form of Fe(OH)flocculent precipitate and the Potassium Chloride (KCl) and KF solution are recycled. This invention has these advantages: adding peroxide to the titanium ferrum powder can oxidize Feinto Feand adding KCOsolution to clean element Fe out by a form of Fe(OH)flocculent precipitate, and the hydrofluoric acid (HF) can be recycled which can realize the HF zero polluting discharge.

Potassium fluotitanate manufacture and device background

An electromagnetic induction melting furnace to control an average nominal diameter of the TiC cluster of the Al&#x2014;Ti&#x2014;C alloy includes a main body containing the melted alloy; and a multi-layer coil disposed on the main body, wherein a frequency of the alternative current of each coil of the multi-layer coil is different, and the alloy is heated by inducing a magnetic field generated by the alternative currents. The selection of the frequency and the changeable magnetic field may reduce the cohesion force between the TiC grains of the Al&#x2014;Ti&#x2014;C alloy to control the average nominal diameter of the TiC cluster.
