Embodiment 1

[0038] Each component is weighed according to the following mass percentage: 55.9% Fe 2 o 3 , 18% NiO, 16% ZnO, 3.5% CuO, 1.8% Co 2 o 3 , 1.3% MnCO 3 , 0.5% V 2 o 5 , 3.0% magnesium chloride hexahydrate.

[0039]After mixing the weighed components, water was added thereto, and then the obtained mixture was ball-milled for 15 hours to obtain a ball-milled product. The prepared primary ball milling product was then dried, and after drying, the first ball milling product was pre-calcined at a pre-calcination temperature of 1060° C. and a pre-calcination time of 3 hours to obtain a pre-calcined product. After the calcined product is cooled, water is added to the pre-calcined product, and then ball milled for a second time. The time of the second ball milling is 4 hours to obtain a second ball milled product. After the secondary ball milling product is dried, the secondary ball milling product is pressed and molded to obtain a molded product, and the molding pressure is 2.5*...

Embodiment 2

[0041] Each component is weighed according to the following mass percentage: 59.1% Fe 2 o 3 , 15% NiO, 15% ZnO, 2% CuO, 2.0% Co 2 o 3 , 1.6% MnCO 3 , 0.8% V 2 o 5 , 4.5% magnesium chloride hexahydrate.

[0042] After mixing the weighed components, water was added thereto, and then the obtained mixture was ball-milled for 20 hours to obtain a ball-milled product. The prepared primary ball mill product is then dried, and after drying, the first ball mill product is pre-calcined at a pre-calcination temperature of 1080° C. to 1090° C. and a pre-calcination time of 5 hours to obtain a pre-calcined product. After the calcined product is cooled, water is added to the calcined product, and ball milling is carried out for a second time. The second ball milling time is 6 hours to obtain a second ball milled product. After the secondary ball milling product is dried, the secondary ball milling product is pressed and molded to obtain a molding, and the molding pressure is 2.3*10 ...

Embodiment 3

[0044] Each component is weighed according to the following mass percentage: 54.1% Fe 2 o 3 , 15% NiO, 18% ZnO, 3% CuO, 2.0% Co 2 o 3 , 1.6% MnCO 3 , 0.8% V 2 o 5 , 5.5% magnesium chloride hexahydrate.

[0045] After mixing the weighed components, deionized pure water was added thereto, and then the obtained mixture was ball-milled for 12 hours to obtain a ball-milled product. The prepared primary ball milling product was then dried, and after drying, the first ball milling product was pre-calcined at a pre-calcination temperature of 1070° C. and a pre-calcination time of 4 hours to obtain a pre-calcined product. After the pre-calcined product is cooled, water is added to the pre-calcined product, and a second ball milling is carried out, and the time of the second ball milling is 3-7 hours to obtain a second ball milled product. After the secondary ball milling product is dried, the secondary ball milling product is pressed and molded to obtain a molding, and the moldi...

Abstract

The invention discloses oversized ferrite for a particle acceleration device and a preparation method of the oversized ferrite, aiming at solving the problems that the conventional oversized ferrite has the requirements on oversize and high performance indexes, only can be produced through an adhesive mode and is limited in performance, phenomena such as breakage, layering, deformation, instable indexes caused by the high-temperature action are caused and the production cost is very high. The oversized ferrite is prepared by taking Fe2O3, NiO, ZnO, CuO, Co2O3, MnCO3, V2O5 and MgCl2.6H2O as raw materials. The ratio of the raw materials is adjusted, a sintering process is improved, the problems that the oversized ferrite is broken, layered and deformed in the sintering process and the like are effectively solved, and the prepared oversized ferrite has the advantages of large size and excellent performance. Meanwhile, the oversized ferrite is subjected to one-step integral molding by adopting a sintering mode and is not needed to be adhered through small blocks, the product performance is greatly improved, and the production cost of the product is further reduced.

Description

technical field [0001] The invention relates to the field of materials, in particular to the field of ferrite materials used in particle accelerators, in particular to a super-sized ferrite used in particle accelerators and a preparation method thereof. Background technique [0002] Large ferrite devices are one of the core components of various high-energy particle accelerators. It is mainly used in linear induction accelerators, which can generate accelerating voltage pulses, accelerate tens of kiloamperes of particle beams to hundreds of MeVs, and can absorb electromagnetic waves generated during particle acceleration to ensure the stability of the accelerator operation process. When ferrite is used in a radio frequency linear or cyclotron, an ultra-high frequency accelerating voltage is generated, which can accelerate particles to the energy of several gigaelectron volts. [0003] At present, small-sized ferrite devices (usually with a diameter between a few millimeters...
