Introduction A LiB compound with chemical composition ratio 1∶1 was discovered at 1970s, when it was used as refractory frame in anode materials, Li-30%B alloy, used for thermal battery [1－3]. Structure... boron, purity 99% were used, as raw materials, in which the boron piece was broken into powder passing 0.15 mm screen. The preliminary Li-B alloy was pre- pared directly through thermal reaction synthesis......

Influence of Composition on Properties of BNT-BT Lead-Free Piezoceramics黄新友,高春华,陈志刚,刘会平摘 要:<正>Lead-free piezoelectric ceramics of (Bi1/2Na1/2... on the properties of BNT-BT lead-free piezoceramics were investigated. The results show that the dielectric constant(ε) and piezoelectric strain constant(d33) of materials start increasing and then decreasing......
Berlin Heidelberg 2016 Abstract: The backfill-mining mass ratio is the ratio of the mass of the backfill materials in the goaf to the mass of the produced raw coal during solid backfill mining... to some extent [5-7], the strata weakens significantly compared with traditional caving mining methods [8]. The backfill materials should be timeously backfilled into the goaf when the raw coal is mined......
