1700C High Temperature Alumina Tube Furnace with 18 Inch Heated Zone and Vacuum Sealing Flanges

Product Overview

This high-performance bench-top thermal processing system is engineered for advanced material and chemical research laboratories requiring extreme temperatures up to 1700ºC. Designed with a high-purity alumina refractory chamber and an eighteen-inch heated zone, the equipment provides an optimized environment for sintering new material samples, conducting high-temperature oxidation studies, and performing chemical vapor deposition. The system integrates precision heating with robust atmosphere control, making it an essential tool for R&D facilities focused on technical ceramics, metallurgy, and semiconductor development.

Targeting both academic and industrial sectors, the equipment excels in scenarios where atmospheric purity and thermal uniformity are paramount. Whether utilized for solid-state reactions, crystal growth, or catalyst characterization, this unit offers the flexibility to operate under high vacuum or specialized gas conditions. The inclusion of professional-grade sealing assemblies and gas management ports ensures that researchers can achieve repeatable results across various experimental parameters, from inert gas blanketing to low-pressure vacuum processing.

Reliability is at the core of this system’s design. Utilizing a double-layer steel casing with integrated air cooling, the equipment maintains a safe external surface temperature even during prolonged high-temperature cycles. The use of Super 1800 grade molybdenum disilicide (MoSi2) heating elements ensures long-term operational consistency and the ability to withstand the thermal stresses of rapid ramp rates. This focus on engineering excellence guarantees that the unit remains a dependable workhorse in demanding laboratory environments, providing the precision and durability necessary for breakthrough scientific discoveries.
