Abstract

Abstract. The synthesis of BSCCO-2223 superconducting material with varians of doping Pb (BPSCCO-2223) at level of Ca = 2,10 and sintering temperature of 855oC has been done by solid state reaction method. The varians of doping Pb was used for the research are 0,00; 0,01; 0,20; 0,30; and 0,40. Variation was carried out to determine the effect of doping Pb on phase formation superconducting material of BPSCCO-2223 that views based on volume fraction, the degree of orientation and impurities. Calcination was executed for 10 hours at temperature of 800oC and sintering for 20 hours at temperature of 855oC. Result of research shows the increase of doping Pb in the sample could increase volume fraction of BPSCCO-2223 and decrease impurity. Volume fraction value of BPSCCO-2223 that is relatively high is 62,06% on doping Pb 0,40. The lowest volume fraction is 42,14% on doping Pb 0,00. The degree of orientation in the sample without doping Pb is 38.51%, the value of degrees of orientation decreases in the sample with doping Pb 0.10 to 21.81%. Then the degree of orientation will increase along with the increase of doping Pb (0.01-0.04). The degree of orientation in sample of doping Pb 0.40 is 38.13%. Besides the addition of doping Pb will decrease the value of impurities. The lowest impurity value of is 37,94% on doping Pb 0,40. Result of SEM shows that all samples have shown that layers arranged in the direction of the empty space between the plates (void) is relatively small.

Abstract

Abstract. Research on the effect of Pb doping is 0; 0.1; 0.2; 0.3 and 0.4 to the phase growth of the Bi-2212 Ca 1,10 superconducting material was carried out by the solid method at a calcination temperature of 800°C for 10 hours and sintering temperature of 830°C for 20 hours. The effect of Pb doping on the phase growth of superconducting material can be seen by volume fraction, impurity, and degree of orientation. The results showed that samples without doping Pb (Pb 0) had lower volume fraction values than samples with doping Pb (Pb 0.1-0.4). Addition of Pb doping (Pb 0.1-0.4) will increase the volume fraction. The highest volume fraction (Fv) in doping Pb 0.4 was 80.99%, whereas the lowest volume fraction on doping Pb 0.1 was 67.73%. Samples without doping Pb (Pb 0) had a lower orientation grade value than samples with doping Pb (Pb 0.1-0.4). The addition of Pb doping 0.1 and 0.4 has a higher orientation degree compared to Pb doping of 0.2 and 0.3. The sample with doping Pb 0,1 has the highest orientation degree value that is 24,87%. Based on the SEM results all the seals have shown layers arranged in a direction (oriented) with empty space between the slab (void) is relatively small.
