Small Chlorine Furnace 'Serialization' Starts

An easy-to-understand introduction to the background of the development of small chlorine generators, the specifications of the equipment, and operational points!

We will introduce the small chlorine furnace that our company handles in a series of articles covering: ■ Background of development ■ Impurity removal mechanism inside the chlorine furnace (chloride volatilization method) ■ Specifications and operational points of the equipment First, let's discuss "Why a chlorine furnace?" In recent years, with the miniaturization of semiconductors and the enhancement of battery performance, the management of metallic impurities (conductive foreign substances such as Fe/Cu/Ni) in powder raw materials has rapidly advanced to the ppm to ppb level. Even slight contamination can have a fatal impact on yield and reliability. Common countermeasures include: 1. Wet method (acid treatment): Dissolving and removing metallic impurities with strong acids. 2. Dry method (magnetic separation): Recovering magnetic particles with powerful electromagnets. However, ■ While the wet method has the advantage of uniform removal, it poses challenges such as large amounts of wastewater, unsuitability for water-sensitive materials, and energy burdens from re-drying. ■ Magnetic separation is limited to magnetic particles and is less effective for non-magnetic metal compounds and fine adherents. *For more detailed information, please download the materials or feel free to contact us.*
