熔融浇铸工艺（MCP）在制造各种形状和尺寸的铋锶钙铜氧（BSCCO）2212块状部件方面具有高度的灵活性。MCP还允许在制造过程中集成电流触点，从而生产出可直接集成到电工设备中的高温超导部件。通过机械加工方法对材料进行机械处理的便利性为MCP块状部件提供了更多选择。在自场中可获得2.5 - 4千安/平方厘米的临界电流密度，在完整的棒材中测量到约1千安/平方厘米。在77K时，在大尺寸管材（外径70毫米，长200毫米）中可获得高直流（6.4千安）和交流（10千安）传输电流。已经生产出了不同的原型以及第一个应用——低损耗混合电流引线，还生产出了限流和屏蔽的功能模型。
The Melt Cast process (MCP) is highly flexible to manufacture BSCCO 2212 bulk parts in a large variety of shapes and dimensions. MCP also allows the integration of current contacts during the fabrication process thus leading to HTS parts which can directly be integrated into electrotechnical devices, The ease of mechanical treatment of the material by machining methods offers additional options for the MCP bulk parts. Critical current densities of 2.5-4 kA/cm/sup 2/ are obtained in selffield, about 1 kA/cm/sup 2/ are measured in full rods. High DC (6.4 kA) and AC (10 kA) transport currents are obtained in large tubes (O 70 mm, L 200 mm) at 77 K. Different prototypes and a first application, each of low loss hybrid current leads, have been produced as well as functional models for current limiting and for shielding.<<ETX>>
