Change composition D inIn order to compare the effect of firing compositions C and D in air and that of firing them in argon, additional work was conducted by firing compositions C (96.60% Ag, 1.38% Cu, 0.28% Al, 0.35% Ti, 1.39% Sn) and D in argon at 900ºC (in addition to the 600ºC firing reported in the original paper) for 60 min at a heating rate of 20ºC/min. This work was necessitated by the temperature correction mentioned above. The surface of the thick film with composition C after firing at 900ºC in argon is shown in Fig. 1 of this Erratum. Incomplete melting of silver particles and gaps were observed. Figure 2 of this Erratum shows the surface of the thick film with composition D after firing at 900ºC in argon. Most silver particles melted. However, gaps also occurred. In addition, parts of both thick films (not shown) were burnt out. Photographs of the scratched films of compositions C and D after firing at 900ºC (not shown) are similar to those of the films fired at 600ºC in argon (Fig. 13 in the original paper). Almost the entire substrate was exposed after scratching.In order to study the effect of oxygen during firing, additional work was conducted by firing compositions C and D at 932ºC in argon (rather than air). This firing resulted in more burn-out than firing at 900ºC in argon, as only an ash-like residue remained on the Al 2 O 3 substrate. In contrast, firing at 932ºC in air resulted in a superior thick film with no gaps for both compositions C and D, as reported in
