Problems solved by technology
The invention provides a C/TiN coated Li4SiO4 tritium breeding agent and a preparation method and a preparation device system thereof. The preparation method comprises the following steps: (1) enabling Li4SiO4 particles to be in a fluidized state in a protective atmosphere; (2) mixing the Li4SiO4 particles, titanium source gas and nitrogen source gas on the basis that the step (1) is continuouslycarried out to obtain TiN-coated Li4SiO4 particles; (3) mixing the TiN-coated Li4SiO4 particles obtained in the step (2) with carbon source gas on the basis that the step (1) is continuously carried out; and (4) carrying out gas-solid separation to obtain the C/TiN coated Li4SiO4 tritium breeding agent. The device system comprises a stock bin, a fluidized bed coating device, a titanium source gasification device, a product collection device and a tail gas treatment device. According to the preparation method, the corrosion of Li4SiO4 to a cladding material is overcome, and meanwhile, the stability of the lithium-based ceramic tritium breeding agent in a He-H2/H2O environment is improved.
