Harper International is the world-leader in thermal processing equipment engineered for the battery materials industry, supporting every stage of development – from R&D and pilot scale to full commercial production. Our systems are designed for high-temperature, controlled atmosphere environments and enable seamless batch to commercial scale-up. We specialize in Cathode Active Material (CAM), Anode Active Material, Solid-State Electrolyte, and Thermal Runaway Protection materials. Harper’s portfolio includes Rotary, Pusher, Belt and Vertical furnaces, optimized for precision, reliability, and scalability. We provide worldwide installation and service support to ensure successful project execution and long-term performance.

Harper has designed advanced furnace and kiln systems for some of the world’s leading battery materials companies. We focus on processing in controlled and specialty atmospheric environments and at temperatures from 300 to 3000°C, and offer designs with gas, electric, and microwave heating. Harper’s expertise covers calcination, graphitization, carburization, controlled oxidation, oxide reduction, purification, pyrolysis, drying, reduction, solid-solid reaction, gas-solid reaction, metalizing, debinding, waste remediation and more.

Many companies on the cutting edge of research in new battery materials need assistance in developing and fine tuning their thermal regimes. At Harper’s Technology Research Center, customers can utilize a number of onsite furnaces and kilns, and have Harper’s expertise at their disposal to work through their process development and process optimization. Harper also provides a variety of additional analytical services such as gas analysis (critical to ensuring compliance with environmental regulations) electron microscopy, XRD, BET, and other thermal and elemental analysis.
