Description

一种坩埚用的坯料
技术领域
本发明涉及坩埚用料技术领域,尤其涉及一种坩埚用的坯料。
背景技术
在工业熔炉中,坩埚是其中重要的组成部分。由于工业熔炉一般是应用于金属的熔融,所以对坩埚的质量提出了更高的要求。
现有的工业坩埚,特别是用于电磁的工业熔炉坩埚,因为坩埚还起着发热的作用,所以坩埚用的坯料的导电性能要求较高;同时,由于现有坯料制备的坩埚表面不光滑,坩埚用于金属加热时,很多金属熔融后,会有残渣残余在坩埚表面,一旦温度下降,金属物将会固化在坩埚上,很难去除;且由于现有的配料制作的坩埚的熔点太低,大大限制了其应用金属物的范围。
发明内容
有鉴于此,本发明提供了一种坩埚用的坯料。
一种坩埚用的坯料,所述坯料由如下按质量组份组成:
优选地,所述坯料由如下按质量组份组成:
优选地,所述坯料由如下按质量组份组成:
优选地,所述碳化硅以及石墨的粒径为10‐80微米。
优选地,所述碳化硅以及石墨的粒径为20‐60微米。
优选地,所述氧化铝、氧化钇以及氧化镧粒径为0.05‐10微米。
优选地,所述粘结剂为粘土、植物油、松香、水玻璃以及树脂中的至少一种。
优选地,所述粘结剂为植物油。
本发明的有益效果在于:通过以碳化硅、石墨以及氧化铝为坯料的主体材料,构成坯料的主体,可以使得制作的坩埚强度非常高;以氧化钇以及氧化镧作为加强材料,可以提高制作的坩埚熔点,导电及发热效率高,同时加入粘结剂,可以使得坯料制作坩埚时,更容易成型。
