High-temperature antioxidant graphite crucible
The invention relates to the technical field of graphite crucibles, and discloses a high-temperature oxidation-resistant graphite crucible, which comprises the following raw materials in parts by weight: 100 parts of regenerated graphite powder, 50-70 parts of white corundum particles, 15-25 parts of alumina clinker particles, 5-10 parts of alumina clinker fine powder, 10-20 parts of alpha-Al2O3 micro powder, 15-25 parts of Al4SiC4 ceramic and 35-45 parts of phenolic resin (PF). The technical problem of high-temperature oxidation of a graphite carbon material in the conventional graphite crucible in the periodic smelting process of non-ferrous metals is solved.
本发明涉及石墨坩埚技术领域，且公开了一种高温抗氧化石墨坩埚，包括以下重量份数配比的原料：100份的再生石墨粉、50～70份的白刚玉颗粒、15～25份的矾土孰料颗粒、5～10份的矾土孰料细粉、10～20份的α‑Al2O3微粉、15～25份的Al4SiC4陶瓷、35～45份的酚醛树脂(PF)。本发明解决了目前石墨坩埚在有色金属的周期性熔炼过程中，其中的石墨炭素材料存在高温氧化的技术问题。
