Manufacturing and characterization of a ceramic microcombustor with integrated oxygen storage and release element

Abstract

Manufacturing and characterization of a ceramic microcombustor with integrated oxygen storage and release element. Micromechanics and Microengineering, 25(10) Abstract -A microscale ceramic high-temperature combustor with a built-in temperature sensor and source of oxygen has been designed, manufactured and characterized. The successful in situ electroplating and oxidation of copper, and the use of copper oxide as the source of oxygen were demonstrated. It was shown that residual stresses from electroplating, copper oxidation and oxide decomposition did not cause much deformation of the substrate but influenced mainly the integrity and adhesion of the metal films. The process had influence on the electrical resistances, however. Calibration of the temperature sensor and correlation with IR thermography up to 1000 °C revealed a nearly linear sensor behavior. Demonstration of combustion in a vacuum chamber proved that no combustion had occurred before release of oxygen from the metal oxide resource. Journal of

Systematic variation of design aspects for a significant increase in thermal fracture resistance of alumina microthrusters

“…The two different heater patterns used to achieve heating at central and peripheral areas, respectively, were designed based on thermography images of similar heater designs presented in [20]. Component thickness was chosen within the range of 300-1100 µm found for HTCC microcomponents in literature [8][9][10][11][12][13][16][17][18], many of which also contain cavities with single-sheet membranes [16,17,20,21].…”

Manufacturing and characterization of a ceramic single-use microvalve

“…A full description of the sintering profile can be found in [15]. Table 1 summarizes the main differences between methods A-D. …”

“…For example microthrusters [12][13], microplasma sources [14], and a microcombustor for combusting solid minute samples prior to isotopic measurements of carbon [15], have been manufactured using HTCC. Integrating isolation valves in HTCC, is a step towards realizing a lab on a chip using this technology.…”

“…Presented in [16], is an example of an ongoing effort to make an HTCC lab-on-a-chip for space applications. Among other components, this chip integrates the microplasma source and the microcombustor presented in [14] and [15], respectively, and is an application foreseen for the valve presented here.…”

Extreme-temperature lab on a chip for optogalvanic spectroscopy of ultra small samples - key components and a first integration attempt

“…Residual gas analysis conducted during the combustion of a carbon-rich sample, together with microscopy, showed that oxygen released from the copper oxide reacted with the carbon, and formed carbon dioxide.
