The optimization of the sintering conditions of disk shaped bulk MgB 2 superconductors with respect to the trapped field is described. Series of samples were prepared by varying the sintering temperatures between 700 and 950 C. The temperature range was divided into three regions, namely the low (<750 C), medium (<825 C), and high (>850 C) temperature region. Scanning electron microscopy and X-ray diffraction indicated that homogenous single phase MgB2 bulks were produced in the medium sintering temperature range. At this processing temperature range the highest trapped field was also achieved. Samples of 20 mm in diameter and 7 mm thick produced at 775 C exhibited trapped field of 1.50 T at 20 K.
