Low Temperature Sintering of Silicon Carbide through a Liquid Polymer Precursor

摘要: There exists a need for more developed and advanced cladding material operational nuclear reactors. The current cladding, Zirconium-alloy, is quickly approaching the pinnacle of its ability to handle increasing fuel load demands. Also, as evidenced by incident at Fukushima, it reacted violently with water steam high temperatures, which created hydrogen gas lead subsequent explosions. Therefore, leading investigation replace alloy silicon carbide. Silicon carbide has been processed manufactured through several techniques; however, this study focuses on development use polymer infiltration pyrolysis (PIP) technique. This technique utilizes precursor, AHPCS, in accordance low temperature sintering enhance density procedure environmentally friendly makes pressure processing parameters. achieved was found be 95 percent fully dense In an effort further increase density, nickel nanoparticles were added precursor two different proportions, 5 10 weight percent. obtained densities 96 97 percent, respectively. Hardness values also pure sample, samples. They 2600, 2700 2730 HV, addition recorded hardness values, scanning electron optical microscopy images utilized properly characterize From these instruments, seen that samples appear quite minimal open pores. Lastly, x-ray diffraction patterns appropriately phase each sample assess any additional product formation nanoparticles. It apparent are crystalline from XRD examination. As samples, there appears results promising outlook advancement potential
