| Abstract | Thermal evaporation process has special practical advantages of being technologically simple and being able to carry out with a low cost, which could be applied especially in technologically-under-developing countries. Tin powder was filled in an alumina crucible by volumetric ratios of Sn to Air as 0.17. The porous LiAl5O8 prepared by the reaction bonded sintering was set above the tin powder by 5 mm. Temperatures at 700°C, 800°C, 900°C, 950°C and 1000°C were selected for the evaporation process of tin powder to coat on the porous LiAl5O8 substrate for 6 hours. The coating temperature of 950°C showed a high deposition rate. The SnO2 did not cover all the surface of LiAl5O8. The SnO2 deposited on LiAl5O8 looks like islands pattern. The electrical conductivity measurement showed the present SnO2/LiAl5O8 material system had the electrical conductivity similar to that of the porous LiAl5O8. Deposited amount of SnO2 was not large enough to affect the electrical conductivity of the system. |
