SEM-EDS and XRD results revealed that crystalline phases presented in the devitrified glass–ceramic were barium aluminate (BaAl2O4), barium aluminosilicate (BaAl2Si2O8) possibly with boron associated in its crystal structure, and barium zirconate (BaZrO3). CTE of the devitrified glass–ceramic was in the range of (10.1–13.0) 106 C1. Good adhesion was obtained both in the cases of glass and devitrified glass–ceramic with YSZ and AISI430 stainless steel. Interfacial phenomena between these components were discussed. 2008 Elsevier B.V. All rights reserved. 1. Introduction Solid oxide fuel cells (SOFCs) are a power source producing electricity via an electrochemical reaction. SOFCs have high energyconversion efficiency [1] and are environmentally friendly due to their low pollutant emission [1–3]. Electrochemical reactions in SOFCs occurred at the temperature range of 600–1000 C and required both oxidizing and reducing atmosphere [4]. Planar SOFCs are a type of SOFCs under development. An important consideration in planar SOFCs fabrication is hermetic sealing of all SOFC components, which are solid electrolyte, metallic interconnect, anode and cathode [5]. The seals must be thermochemically and mechanically compatible with other SOFC materials, should have high electrical resistance, and must be stable and long time durable under operating condition under H2 and H2O atmosphere [4,6]. Rigid sealing using glasses or glass–ceramics is a promising option 展开

Fig. 1 shows that diamond particles are dispersed in the copper matrix. Since the diamond particles are easy to be stripped off during mechanical polishing, small pits are left on the surface of samples. When the samples were analyzed by electron probe for carbon, the particles displayed high carbon peaks, as shown in Fig. 2. Fig. 3 exhibits the analyzed result for extracted product of the copper–diamond composite by X-ray diffraction (XRD) analysis. It is shown that three dif- fraction peaks exist, shown as A, B and C, respectively. The interplanar distances corresponding to the three peaks and standard ones for diamond are compared in Table 1. The measured values of the interplanar distances are in good agreement with the standard ones, demon- strating that the extracted product should be the carbon in diamond state. Fig. 4(a) gives a TEM micrograph showing distribution and morphology of diamond particles (indicated as A, B, and C) in the copper–diamond composite. The calibration of interplanar distance for diffraction rings in Fig. 4(b) was given in Table 2. Compared to Table 1, it is also demon- strated that the calibrated interplanar distances for the diffraction rings conform to the standard ones of diamond. Therefore, it is believed that the graphitization of diamond particles hardly occurs after sintering at 1150–1220 K in the copper–diamond composite. Although diamond is a metastable allotropic modifica- tion of carbon, the graphitization of diamond particles in the copper–diamond composite did not occur, or the degree of graphitization was too small to be found. It is believed that the beginning temperature of graphi- tization would be associated with the purity of diamond powders. The impurities such as some metallic elements reduce the beginning temperature of diamond graphitiza- tion. When diamond is fabricated by the static synthesis method, Fe and Ni are often used as catalysts and are present in diamond as impurities to decrease the beginning temperature of graphitization [6]. It is understandable that both for the graphitization and its reverse reactions, their activation energies can be decreased by catalytic agents. Compared with the diamond fabricated by static synthesis, the diamond powders prepared by explosion method do not contain metallic impurities, thus leading to an obvious increase in the beginning temperature of graphitization. Hence, the detonation synthetic diamond might be more resistant to graphitization and probably suitable for the electric contact materials. 展开

Experimental Method All experiments were carried out in a high-pressure CO2 apparatus (Speed-SFE from Applied Separations) (see Figure 1) with a 300-mL extractor designed for a maximum pressure of 690 bar and a maximum temperature of 250 °C. The volume of the extractor had to be reduced to 50 mL by a metallic cylinder, which tightens to the extractor wall, because as preliminary tests showed the equilibrium cell has to be completely filled with material. Otherwise, diffusion is the limiting factor and time for reaching equilibrium was too long. The extraction vessel was filled with compressed CO2 by an air-driven pump at closed outlet valves and under static conditions, which means desired pressure and temperature; the cell was incubated for 15 h, maintaining these conditions to reach equilibrium. In preliminary experiments the equilibrium time of 15 h was determined to reach equilibrium. CO2 Sampling. At equilibrium a CO2 phase sample is taken by opening the outlet valve and expanding a certain amount of CO2-substance mixture into a cooling trap filled with toluene, which has the highest solubility for the measured substances under atmospheric conditions. The pure gaseous CO2 passes a rotameter, showing the actual flow rate, and a gas flowmeter for determining the expanded CO2 amount. The content of the cooling trap was filled up with toluene to 30 mL and analyzed by a gas chromatographic method using an electron capture detector (GC-ECD). With the mass of expanded CO2 and composition of the cooling trap solubility at a certain pressure and temperature was calculated. Sampling was repeated four times at a given pressure and temperature and the standard deviation was lower than 5%. Gas Chromatographic Method. The tolueneflame retardant mixture of CO2 sampling was analyzed in a gas chromatograph (HP 5890 Serie II) with an ECD using a capillary column (type HP-1, 12 m 0.2 mm 0.2 ím). The injector temperature was held constant at 290 °C and the detector temperature at 300 °C. The oven temperature was held constant at 290 °C. Calibration with different amounts of HBCD and TBBA in toluene has been done before determining the linear range of calibration line and retention time of substances 展开
