A coal tar pitch with QI was used to prepare MCMBs. Some properties of the coal tar pitch are summarized in Table 1. During the preparation of MCMBs, an additive of alumina powders (commercial product, analytical reagent) with size of less than 2 μm was added into the parent pitch. The morphology of the alumina powder is shown in Fig. 1.
