作为优选,所述堇青石、氧化锆和莫来石的粒度都不大于200目;所述氧化铝粉粒径不大于2mm。
作为优选,所述红柱石为生料红柱石;所述红柱石为湿粉碎;所述高岭土为悬浮液状态。
作为优选,所述基体与所述工作层的厚度比例为7:3。
作为优选,所述基体的成分为:莫来石30wt%~40wt%、刚玉10wt%~20wt%、高岭土10wt%~20wt%、氧化铝粉10wt%~20wt%、石英10wt%~20wt%、堇青石5wt%~10wt%;所述工作层的成分为:钾长石10wt%~15wt%、熔融石英10wt%~20wt%、莫来石10wt%~20wt%、红柱石12wt%~18wt%、刚玉10wt%~20wt%、氧化铝粉10wt%~20wt%、氧化锆粉10wt%~20wt%。
作为优选,所述基体的成分为:莫来石30wt%~40wt%、刚玉10wt%~20wt%、高岭土10wt%~20wt%、氧化铝粉10wt%~20wt%、石英10wt%~20wt%、堇青石5wt%~10wt%;所述工作层的成分为:钾长石13wt%~14wt%、熔融石英10wt%~20wt%、莫来石10wt%~20wt%、红柱石12wt%~18wt%、刚玉10wt%~20wt%、氧化铝粉10wt%~20wt%、氧化锆粉10wt%~20wt%。
作为优选,所述基体的成分为:莫来石35wt%、刚玉15wt%、高岭土15wt%、氧化铝粉15wt%、石英12wt%、堇青石8wt%;所述工作层的成分为:钾长石13wt%、熔融石英14wt%、莫来石14wt%、红柱石14wt%、刚玉15wt%、氧化铝粉15wt%、氧化锆粉15wt%。
作为优选,所述基体的成分为:莫来石30wt%、刚玉20wt%、高岭土10wt%、氧化铝粉20wt%、石英10wt%、堇青石10wt%;所述工作层的成分为:钾长石14wt%、熔融石英14wt%、莫来石14wt%、红柱石14wt%、刚玉14wt%、氧化铝粉15wt%、氧化锆粉15wt%。
一种匣钵的制造工艺,包括如下步骤:
1)将基体各原料按配比混合,在搅拌机中搅拌30分钟;以45MPa的压力干法成型;
2)将工作层各原料按配比混合,在搅拌机中搅拌30分钟;
3)将步骤2)中经过混合搅拌的工作层原料均匀撒在匣钵基体工作面上,以60MPa的压力将工作层原料压在基体工作面上;
4)将步骤3)中得到的胚件在1300~1350℃下烧结2小时,然后自然降温,制得匣钵。
作为改进,所述步骤3)中以60MPa的压力将工作层原料压在基体工作面上之后,以同样的压力再压1次。
本发明的有益效果:
(1)使用寿命长,经过多次试验发现,本发明提供的匣钵用于锂电池正极材料焙烧时,平均使用次数可高达30次,远高于目前市场上流通的用于锂电池正极材料焙烧的匣钵。
(2)结合牢固,经过多次试验发现,由于本发明提供的匣钵的工作层中加入了钾长石,在高温烧结时,除却钾长石自身在高温下熔融黏度高,具备高温胶结的作用外,可能与刚玉等反应形成了新的物质,所形成的新物质的结合力比单纯的钾长石的高温胶结作用结合力更大,可以极大提高工作层各成分之间的结合力,同时也极大提高工作层与基体之间的结合力,使匣钵整体结合牢固,利于增加匣钵的使用寿命;由于本发明提供的匣钵的工作温度为900~1000℃,而钾长石熔点在1150±20℃范围内,从而可以避免因匣钵内钾长石熔融导致结合力降低。
(3)抗热震性强,由于本发明提供的匣钵的工作层中加入了氧化锆粉,大大提高了匣钵的抗热震性,提高匣钵的使用寿命。
(4)抗腐蚀性能优异,由于工作层的存在,在使用寿命内,工作状态下,既不会出现锂电池正极材料向匣钵内腐蚀渗透,也不会出现匣钵内的成分向锂电池正极材料渗透。
(5)成本低廉,本发明提供的匣钵中钾长石价格低廉,单位匣钵所需材料总价格不高,且因钾长石的存在降低了烧结温度,进一步降低了成本,便于市场化。
具体实施方式
实施例一
一种匣钵,包括底面和侧壁,所述底面和侧壁形成用于焙烧的凹腔,所述匣钵包括基体和工作层,所述工作层在基体工作面上;所述基体的成分为:莫来石35wt%、刚玉15wt%、高岭土15wt%、氧化铝粉15wt%、石英12wt%、堇青石8wt%;所述工作层的成分为:钾长石13wt%、熔融石英14wt%、莫来石14wt%、红柱石14wt%、刚玉15wt%、氧化铝粉15wt%、氧化锆粉15wt%。所述堇青石、氧化锆和莫来石的粒度不大于200目;所述氧化铝粉粒径不大于2mm;所述基体与所述工作层的厚度比例为7:3;所述基体中先以高岭土形成悬浮液,在所述悬浮液中加入基体的其余原料,如此可以防止高岭土没有来得及完全化开,使得制得的匣钵成型时没有充分获得可塑性。同时,在高岭土悬浮液中加入氧化铝粉可以对高岭土起到增进研磨作用,以这种方法可以使高岭土均匀配置,还可以使胚料获得最大含量的莫来石相。工作层中的红柱石采用生料红柱石,当采用煅烧红柱石时,煅烧原料阶段形成的莫来石骨架在粉碎时受到严重破坏,使得制成品中莫来石网络难以形成,而采用生料红柱石,莫来石化过程在烧制成品时进行,制成品中可形成完整的莫来石化网络,从而提高制成品的荷重软化温度,同时为了使红柱石有更好的烧结性,对红柱石采用湿粉碎;匣钵的工作层中加入氧化锆粉,大大提高了匣钵的抗热震性,提高匣钵的使用寿命;工作层中的钾长石除却自身在高温下熔融黏度高,具备高温胶结的作用外,可能与刚玉等反应形成了新的物质,所形成的新物质的结合力比单纯的钾长石的高温胶结作用结合力更大,可以有效提高基体和工作层之间的结合力,同时也可以有效提高工作层各成分之间的结合力,使匣钵整体结合牢固,有利于提高匣钵使用寿命;由于本发明提供的匣钵的工作温度为900~1000℃,而钾长石熔点在1150±20℃范围内,从而可以避免因匣钵内钾长石熔融导致结合力降低;加入钾长石后还可大幅度降低烧结温度,从而降低生产成本;钾长石还可以加速莫来石形成速度,以提高匣钵的荷重软化温度。
尽管钾长石有着诸多优点,但在使用过程中经过多次试验发现:钾长石含量低于5wt%时,极易出现结合力不足的问题,导致工作层与基体脱离;钾长石含量高于于20wt%时,工作层玻化现象严重,耐热震性不足,容易破裂;钾长石含量在10wt%~15wt%时上述结合力不足的问题和工作层玻化现象严重问题大为改善;尤其是钾长石含量在13wt%~14wt%时,可以同时兼顾结合力问题和工作层玻化问题,使两者都得到最佳效果。
所述匣钵的基体和工作层的各原料分别按配比混合并分别在搅拌机中搅拌30min;所述匣钵的基体以干法压制成型,成型压力为45MPa,经混合后的工作层原料均匀撒在基体工作面上以60MPa的压力将工作层原料压在基体工作面之上;烧结温度为1300℃,烧结时间为2小时,然后自然降温,制得匣钵。搅拌时间选择30min兼顾了成本和材料的均匀性,保证匣钵的成型质量和机械强度;工作层选择以60MPa的压力压在基体之上,是因为在制造过程中发现,压力小于60MPa时容易造成工作层与基体结合不牢,压力大于60MPa时容易使基体变形,还会造成资源的浪费;烧结时间选择2小时兼顾了成本和匣钵的质量,保证产品尽可能莫来石化。
