KSL-1700X-O2 Atmosphere-Controlled Box Furnace for Sintering in Air, Oxygen, and Inert Gases
The KSL-1700X-O2 furnace is engineered to meet the demanding requirements of sintering materials in controlled atmospheres including air, pure oxygen, and inert gases. Its design supports the preparation of high purity oxide ceramics and is particularly suited for processing high nickel battery cathode materials. The furnace chamber measures 200 x 200 x 200 mm (8 x 8 x 8 inches), providing an 8-liter volume for sample loading up to 100 kg.
Constructed with high-grade alumina fiber bricks and coated with high purity Al2O3, the chamber offers excellent thermal insulation and durability. Heating is provided by six replaceable MoSi2 elements (30 x 360 mm), capable of operating from 600°C to 1700°C in air or oxygen, and 1000°C to 1600°C under inert atmospheres. The furnace is not designed for high vacuum but maintains a vacuum level around 500 torr at elevated temperatures.
Key Features
- Atmosphere control for air, 100% oxygen, and inert gases with built-in pressure gauge, vacuum valves, and gas flow meters.
- Robust double-layer steel structure with water-cooled front door and air-cooled shell for safety and thermal management.
- Advanced temperature control via Eurotherm 3000 controllers with 0.1°C resolution and dual B-type thermocouples for monitoring and alarms.
- Programmable 24-segment temperature profiles with over-temperature and current protection, plus secondary safety controller.
- Pressure control system maintaining constant pressure from -0.06 to 0.03 MPa with high/low pressure alarms and inert gas purging modes.
- Vacuum pump included to assist purging and maintain chamber pressure below 760 torr; low vacuum achievable due to insulation material.
- Data logging of temperature and pressure profiles saved to built-in PC; optional remote WIFI operation available.

Typical Applications
This furnace is widely used in research and development of high purity oxide ceramics, sintering of battery cathode materials with high nickel content, and other advanced material synthesis requiring controlled atmosphere and high temperature processing.
Configuration & Operating Notes
The furnace includes a vacuum pump to assist in purging and maintaining low vacuum conditions. Two gas flow meters allow precise control of inert and oxygen gas flows. The system requires an external water cooling setup delivering 58 liters per minute for optimal operation. The power cable is supplied without a plug, and additional certifications such as NRTL or CSA are available upon request at extra cost. For oxygen-sensitive materials, a hydrogen furnace is recommended instead.
