Ceramic crucible for nickel-based superalloy and preparation method
The invention belongs to the field of refractory materials, and relates to a ceramic crucible for nickel-based superalloy. According to the ceramic crucible for the nickel-based superalloy, pure fine powder is used as a raw material, and whiskers are used for reinforcing and toughening; the pure fine powder is aluminum oxide and nickel carbonate, and the crystal whiskers are zirconium oxide crystal whiskers; and the novel ceramic crucible for the nickel-based superalloy is prepared by the following steps: uniformly mixing the raw materials, adding a binding agent, conducting granulating, and carrying out cold isostatic compaction and sintering at high temperature. Pure fine powder is selected as a raw material, the crystal whiskers are used for strengthening and toughening, and the prepared ceramic crucible is good in component consistency, uniform and compact in structure, low in apparent porosity, small in pore diameter, uniform in pore diameter distribution, excellent in thermal shock resistance and not prone to being permeated and eroded by nickel-based high-temperature alloy liquid. The prepared ceramic crucible can effectively solve the problem of inclusion of a nickel-based high-temperature alloy refractory material, so that the requirement of high-quality nickel-based high-temperature alloy is met.
本发明属于耐火材料领域，涉及一种镍基高温合金用陶瓷坩埚。涉及的一种镍基高温合金用陶瓷坩埚采用纯细粉作为原料，以晶须增强增韧；所述的纯细粉为氧化铝和碳酸镍，所述晶须为氧化锆晶须；新型镍基高温合金用陶瓷坩埚所用原料经混合均匀后，加入结合剂造粒，冷等静压成型并高温烧成。本发明选取纯细粉作为原料，以晶须增强增韧，制备的陶瓷型坩埚成分一致性好，结构均匀致密，显气孔率低，孔径小且分布均匀，抗热冲击能力优异，不易被镍基高温合金液渗透和侵蚀。所制备的陶瓷坩埚能有效解决镍基高温合金耐火材料夹杂的问题，从而满足高品质镍基高温合金的要求。
