Description
技术领域
本发明涉及赛隆材料技术领域,具体涉及一种赛隆电加热新材料的烧结工艺。
背景技术
赛隆(Sialon)为组成范围很宽的固溶体。赛隆制品的性能与其组成和烧结致密程度有密切关系。赛隆抗氧化性、抗热震性、抗碱及渣侵蚀的性能尤为突出,赛隆材料的使用范围正在逐步扩展;赛隆的烧结方式有热压烧结、和无压烧结等,赛隆通过烧结主要为了增加烧结体的密度与韧性以提高材料的强度,其中加压烧结是通过在烧结过程中,对生坯施加外部压力,同时升温并在较高温度保温,这样生坯即在高温和压力的双重作用下,内部的空隙被压缩,从而达到致密。然而,目前的加压烧结设备,多只能朝一个方向施加压力,因此仅能制备形状规则的产品如圆柱、长方体等,对于生产其它形状的产品较为困难。无压烧结由于在烧结过程中不对产品施加外力,则可以生产形状各异的产品,但由于没有压力作用,生坯内部空隙难以排除,产品难以致密,达不到好的性能。为提高传统传统工艺生产赛隆的强度,本发明提出了一种赛隆电加热新材料的烧结工艺。
发明内容
针对上述存在的问题,本发明提出了一种赛隆电加热新材料的烧结工艺。
为了实现上述的目的,本发明采用以下的技术方案:

(1)赛隆电加热新材料的原料由赛隆电加热新材料的原料由氮化硅粉末、添加剂组成;所述添加剂为氧化物、氮化物、碳化物中的一种或几种;
(2)将氮化硅粉末和添加剂置于溶剂中均匀混合,再将溶剂蒸干;
(3)将上述原料投入烧结炉中,加热升温至1400~1900℃,保温0.1-20h,保温结束后,再升温至1500~2200℃下进行二次烧结,保温0.1-40h,保温结束后,并随炉自然冷却至室温,得到烧结体;
(4)对烧结体进行表面磨削、去毛刺处理,即可得到赛隆电加热新材料。
优选的,所述步骤(1)中纳米氮化硅新材料的原料按照重量份计为:氮化硅粉末50~65份、添加剂25~55份。
优选的,所述步骤(1)中纳米氮化硅新材料的原料按照重量份计为:氮化硅粉末55份、添加剂30~40份。

优选的,所述氮化硅粉末α-相含量为90~97%。
优选的,所述一次烧结温度为1500℃。
由于采用上述的技术方案,本发明的有益效果是:采用本发明的烧结工艺不仅必须克服了传统赛隆材料的脆性,还显著提高了获得高强度的赛隆;通过改进工艺,使得产品在没有压力的情况下获得高致密产品,且产品形状不受限制,并可实现大规模批量生产,获得的产品强度大于900MPa。
