Abstract

The Zeolite Crystal Growth (ZCG) facility aims to provide a versatile experimental facility for crystal growth studies on the International Space Station (ISS). The first hardware in a series of furnaces is the ZCGFU (ZCG-Furnace Unit) and the Improved Zeolite Electronic Control System (IZECS) scheduled to fly on UF-1 (11/29/2001) to the ISS. This facility meets the initial requirements of CAMMP, its commercial partners, and the scientific community at large. The crystal growth capability at this time consists of this furnace unit and its electronic control system, and mechanically complex, crystal growth autoclaves suitable for solution crystal growth. These autoclaves typically contain two precursor solutions that are mixed automatically on orbit. The ZCG-FU contains 19 tubes operating at three concentric temperature zones in the range 90-200 °C. ZCG-FU and IZECS will operate through ISS Increment 6. The second furnace following ZCG-FU is the Zeolite Crystal Growth High Temperature Furnace (ZCGHTF) for solution crystal growth of advanced materials at higher temperatures up to 350 °C. The ZCG-HTF is expected to fly on 13A.I (08/2003). This design includes increased autoclave size to obtain higher crystal yield than the existing furnace (ZCG-FU). Both furnaces are controlled by IZECS, which provides monitoring of critical parameters, data logging, safety monitoring, and operator interfacing and ground control capability.
