Preparation method for zirconolite type manmade rock
The invention discloses a preparation method for a zirconolite type manmade rock. The preparation method is characterized by comprising the following steps: preparing materials from CuO powder, CaO powder, Ti powder, TiO2 powder and ZrO2 powder; performing dry-process ball-milling on the raw materials, uniformly mixing the raw materials and enabling the raw materials to pass through a 100-mesh sieve; feeding 10-50g of the mixed materials into a stainless steel mould, and pressing the mixed materials into cylindrical blank; introducing the blank into a self-propagating quasi-isostatic device, igniting the blank through a tungsten filament to react, and applying pressure of 50-200MPa after the combustion reaction is ended, thereby preparing the high-compactness zirconolite type manmade rock. The preparation method disclosed by the invention can be used for synthesizing the zirconolite type manmade rock within several minutes by adopting a self-propagating high-temperature combined quick compacting process, has the advantages of being high in synthesis speed, high in efficiency, high in reaction temperature, high in product purity, low in energy consumption, simple, and the like; the prepared zirconolite type manmade rock is suitable for long-term safety solidification treatment and disposal of actinide in high-level waste.
