Fabrication of uniform ZrC coating layer for the coated fuel particle of the very high temperature reactor

TEM study of the reaction mechanisms involved in the carbothermal reduction of zirconia

“…Many routes were developed to synthesize powders -Selfpropagated High-temperature Synthesis (SHS) reaction, [5][6][7][8] laser pyrolysis, [9][10][11][12][13] fusion synthesis by arc-melting, 14 mechanosynthesis [15][16][17] or thin films by Chemical Vapour Deposition (CVD 18,19 ). Each of these synthesis routes presents both advantages and drawbacks, but they are generally used to produce limited quantities of carbides.…”

The phase equilibria in the Pr–Si–Zr ternary system at 773K

“…Due to the favorable neutronic properties like low neutron absorption, good elevated-temperature mechanical properties and outstanding corrosion resistance in pressurized heavy water reactor condition, Zr-based alloys are used as important structural materials for reactor core components [1][2][3]. For the future nuclear reactors like gas fast reactors, the cores may work at high temperatures range from 500 • C to 1000 • C. Moreover, current trends towards extended burn-up of the nuclear fuel in pressurized water reactors have accentuated the demand for Zr-based alloys with higher uniform corrosion resistance under irradiation and high temperature mechanical properties [4].…”

Experimental study of Al–Zr–Y system phase equilibria at 773K

“…Therefore, the properties of this intermetallic compound have been extensively studied [5,6]. Moreover, the Zr 3 Al-based alloys have some excellent properties like low neutron absorption cross-section, good elevated-temperature mechanical and anti-corrosion properties, thus they are widely used for reactor core components [7,8]. Rare earth elements, i.e.…”
