The present invention discloses a triodic rectifier switch having two diodes and one resistor. These compounds have the structure:wherein R1, R2, R3, R4, R5, and Q1 are defined herein. It has a layered lattice structure with hexagonal carbon layers and an expanded interlayer space, and its density determined in accordance with He equilibrium pressure density measuring method changes according as pre-equilibrium He pressures and falls in a range of 0. The tools can include, but are not limited to a cracker, a pulverizer, a wood shear, an ironrail cracker and a grapple.
