August 2015 – Harper Now Offering Microwave Testing in Technology Research Center for New Material Process Development

Carbon powderHarper International is excited to offer Microwave testing as part of our Ignite™ program in our Research and Pilot facility.

Microwave heating provides significant benefits over conventional heating because the material to be processed is the heating element. Since most ceramic materials have low conductivity and in conventional processing the heat transfer occurs by conduction, the processes are slow. Thermal conductivity is not an issue with microwaves. Another key benefit is a high equipment utilization ratio due to the drastic reduction in insulation of the furnace in microwave heating.

All non-metallic and electrically non-conducting materials can be tested in temperatures ranging from 600°-1800°C. Applications include, but are not limited to; ceramic processing, powders, shaped ceramics, activated carbon, battery materials and food processing.

Harper’s laboratory team is available to support testing for a wide range of applications and materials. Testing can be performed in small batches to small scale continuous processes in small rotary calciners or vertical processing reactors, and Harper can help take your idea from spark to finish. With over 29 years of experience with Microwave testing, you can trust Harper’s team of engineers to take your unique process from the lab to full commercialization.

July 2015 – Harper Reports Success at Pre-Conference Site Visit & Tour

Harper OvenIt was a successful event for the GOCarbonFibre 2015 pre-conference site visit at Harper International in Buffalo, New York. Attendees received the unique opportunity to tour Harper’s research and development Microline™ and 3 Meter Oxidation Oven. Harper’s PhD and technical experts led small group tours of each unit operation, including the Oxidation Oven, LT and HT Furnace systems, UHT Furnace system, and advanced control systems, offering insight into the advantages of this state-of-the-art line. The day culminated in a networking dinner next to historic Niagara Falls.
