Definitions

  • fly ash has been disposed of as waste, but in recent years, as a result of its increasing use as a concrete admixture, the amount of fly ash discarded has been decreasing. However, most of its use depends on the cement sector, and there is concern that if demand for cement stagnates, fly ash, which is disposed of, will start to increase again. For this reason, the development of new uses for fly ash has become an urgent issue.
  • the composition of fly ash varies depending on the raw material coal and the place of origin (power plant, country).
  • Patent Document 1 Japanese Patent Application Laid-Open No. 6-316815
  • Patent Document 1 has 20 to 40% Al 2 O 3 , 35 to 50% SiO 2 , and 15 to 35% Ca O.
  • fly ash fibers characterized by containing 3-12% Fe 2 O 3 and 2-5% Mg O.
  • the Fe 2 O 3 content also contained in fly ash fiber is 3 to 12%. It is desirable that this content is as low as possible. Also, the Fe 2 O 3 content is high. Increasing the amount increases the degree of coloration of the fly ash fiber, which is not preferable. Therefore, a Fe 2 O 3 content of 12% or more is problematic and should be avoided. ”(Ibid., Paragraph).
  • Patent Document 2 Japanese Patent Application Laid-Open No. 2018-531204 (hereinafter, Patent Document 2) is a mineral fiber containing Al 2 O 3 , SiO 2 , CaO, MgO, and Fe 2 O 3 as components. It discloses a mineral fiber characterized by a Fe 2 O 3 content of 5 to 15%. The document states that "increased iron content tends to color the mineral fibers, which is not particularly desirable for applications where the mineral fibers remain visible" (ibid., Paragraph [0005]).
  • JP-A-6-316815 Special table 2018-531204 JP-A-60-231440 JP-A-10-167754
  • the CaO content is preferably 5% by mass or more and 30% by mass or less. If the CaO content is less than 5% by mass, the melting start temperature of the material becomes high, which is not preferable from the viewpoint of energy saving.
  • the CaO content is preferably 10% by mass or more. On the other hand, if the content is more than 30% by mass, the viscosity of the melt is too low and it becomes difficult to form threads.
  • CaO may be abbreviated as C component, and the CaO content may be indicated as [C].
  • the inorganic material of the present invention there are no restrictions on the raw material as long as the ratios of SiO 2 , Al 2 O 3 , Fe 2 O 3 and Ca O fall within the above range. Therefore, compounds of SiO 2 , Al 2 O 3 , Fe 2 O 3 , and Ca O can be prepared as starting materials, but a silica source rich in SiO 2 and an alumina source rich in Al 2 O 3 can be used. , Fe 2 O 3 rich iron oxide source and Ca O rich calcium oxide source are blended and used as a starting material from the viewpoint of raw material cost.
  • the silica source include, but are not limited to, amorphous silica, silica sand, fumed silica, and volcanic ash.
  • fly ash, clinker ash, or coal gasification slag can be used as the silica alumina source
  • copper slag can be used as the iron oxide source
  • steel slag can be used as the calcium oxide source.
  • most of the silica alumina source, the iron oxide source, and the calcium oxide source can be covered by industrial waste.
  • volcanic rocks such as basalt and andesite can also be used as silica-alumina sources.
  • Example 1 30 parts by mass of FA (1) and 70 parts by mass of BA (1) were blended.
  • This sample has the same composition as the sample 3 used in the above-mentioned prior test.
  • the component ratio of this sample is [S] + [A]: 60% by mass, [A] / ([S] + [A]): 0.20, [F]: 16% by mass, [C]: 17 It is by mass% (Table 6).
  • ultrafine fibers (mineral fibers) having a diameter of 50 ⁇ m or less were obtained within 5 hours after the temperature in the furnace reached 1350 ° C. The obtained fiber had a strength that could not be easily cut even when pulled by hand.
  • the fiber sample was irradiated under the following conditions.
  • ⁇ Vickers hardness test> A Vickers hardness test was performed on the fiber sample before irradiation and the fiber sample after irradiation.
  • the test equipment used is the Reichert-Jung Microduromat 4000E and the Leica Telatom 3 light microscope. Considering that the width of the fiber sample is about 20 ⁇ m, the force applied to the sample surface was set to 10 gF (0.098N). As a result of measuring 17 points for each of the samples before and after the irradiation, it was 723 ⁇ 24 kgF / mm 2 before the irradiation and 647 ⁇ 19 kgF / mm 2 after the irradiation.
  • Example 2 The sample was prepared according to the raw material mixing ratio shown as Example 2 in Table 6.
  • the component ratio of this sample is [S] + [A]: 60% by mass, [A] / ([S] + [A]): 0.25, [F]: 19% by mass, [C]: 13 It is by mass% (Table 6).
  • the sample melted and dropped within 5 hours after the temperature in the furnace reached 1350 ° C., and ultrafine fibers (mineral fibers) having a diameter of 50 ⁇ m or less were obtained.
  • the obtained fiber sample was substantially composed of only an amorphous phase, and could not be easily cut even when pulled by hand. The amorphous property is maintained even by irradiation, and the Vickers hardness retention rate is at the same level as in Example 1. As described above, this material is extremely excellent in radiation resistance.
  • the inorganic material of the present invention has excellent radiation resistance, it can be used in the fields of nuclear power, aerospace, and medical care. By using it for the radiation-exposed part of equipment / equipment / member in these fields, the radiation deterioration of the radiation-irradiated part can be suppressed.
