Inorganic Chemicals/Nano Materials -

Brilliant paints. Versatile building products. Advanced catalysts. As the chemical industry broadens into ever more complex and value-added products with new powders and pigments, new additives, new coatings and super conductors, Harper calcination and reactor systems match the industry's escalating need.

Harper rotary tube calciners, graphite tube reactors, mesh belt furnaces and other advanced, custom-designed thermal equipment provide the precision control over temperature, atmosphere, material flow and residence-time distribution required for consistent and uniform material processing.

Aluminas, silicas, cobalt, iron oxide, barium titanate and zirconia are examples of inorganic chemicals processed under controlled-atmosphere environments, including hydrogen, at temperatures up to 3,000°C.

Thermal waste processing applications include processing of refinery waste, nuclear waste, scrap tungsten, spent catalysts and contaminated lighting glass.

Across all of these uses, Harper equipment

provides outstanding reliability, versatility

 and economy. Advanced sealing systems, choice of tube or muffle materials including quartz, graphite, high temperature alloys, and gas and electric heating, enable optimum performance in diverse process applications. And before committing to production equipment, you can develop and refine your process parameters at Harper's pilot facility.
