High Temperature Horizontal Electrical Assisted Sintering Furnace with 3KW Programmable Power Source for Advanced Ceramic Materials

Product Overview

This high-temperature horizontal thermal processing system represents a significant advancement in material science instrumentation, specifically engineered for electric-assisted sintering (EAS) and flash sintering protocols. By combining a precision-controlled 1600°C horizontal tube furnace with an integrated 3KW programmable AC power source, the equipment allows researchers to investigate the transformative effects of electric fields on ceramic densification. This integrated approach enables the simultaneous application of thermal energy and controlled electrical currents, facilitating the sintering of materials at significantly lower temperatures and shorter durations than traditional methods.

The system is primarily utilized in cutting-edge laboratory environments and industrial R&D centers focusing on technical ceramics, solid-state battery electrolytes, and high-performance composites. Its horizontal configuration is optimized for specialized sample loading, featuring a slidable flange system that streamlines the placement of delicate ceramic specimens within the high-heat zone. Beyond flash sintering, the unit serves as a versatile platform for atmosphere-controlled heat treatments, chemical vapor deposition (CVD), and powder calcination, making it an indispensable asset for institutions pushing the boundaries of solid-state ionics and structural ceramic engineering.

Engineered for high-duty cycle performance under demanding laboratory conditions, this system emphasizes reliability and precision. Every component, from the high-purity alumina process tube to the platinum electrode feedthroughs, is selected to withstand extreme thermal gradients and electrical loads. This robust construction ensures that users can achieve repeatable, high-density results in every cycle, providing the confidence necessary for peer-reviewed research and the development of commercial-grade advanced materials. The equipment is built to maintain rigorous vacuum integrity and temperature uniformity, meeting the exacting standards of the international material science community.

Key Features

• Integrated 3KW Programmable AC Source: The system includes a dedicated power supply capable of delivering up to 208 VAC with 3000W capacity, allowing for the precise application of electric fields to trigger flash sintering and explore electrical-assisted material transformations.
• Precision Multi-Step Temperature Control: An advanced PID controller manages the thermal cycle through 30 programmable segments with ±1°C accuracy, ensuring the heating rates and soak times meet the strict requirements of complex material synthesis.
• High-Purity Alumina Processing Tube: Equipped with a standard 80mm OD alumina tube, the furnace provides a chemically inert and thermally stable environment suitable for continuous operation at 1600°C, preventing contamination in sensitive ceramic samples.
• Slidable Vacuum Flange and Sample Fixture: The engineering of the right-side flange allows it to slide easily along the support rails, facilitating effortless sample loading and unloading while protecting the internal heating elements and sample alignment.
• Platinum Electrode Feedthroughs: High-conductivity Ø1 mm platinum wires are utilized for the electrical feedthroughs, ensuring stable current delivery up to 15A within the high-temperature zone without oxidation or material degradation.
