本文根据单相的个体特性选择堇青石和ＴｉＣ两相复合制备出了导电型的红外辐射陶瓷材料。对体系电性能进行研究发现，体系电导率值随ＴｉＣ含量的变化呈非线性变化，ＴｉＣ含量在９％ｗｔ以下时，体系电导率在１０￣（－１）Ｓ／ｃｍ以下，而从９％ｗｔ开始，随着ＴｉＣ含量的增加，体系的电导率迅速增加，幅度达几个数量级之多。通过电子探针分析我们认为，材料的导电是由ＴｉＣ相形成的导电通路所提供的，其导通过程是一种逾渗过程。根据渗流理论对体系的导电特性进行分析，可以很好地说明电导率发生的突跃现象，由此得到了本复合体系的导电模型。利用这种模型可以从理论上预测某一给定ＴｉＣ含量时系统电导率值的大小，使体系的电导率可控可调。
In this paper, according to the individual characteristics of single-phase selection of cordierite and TiC two-phase composite prepared conductive infrared radiation ceramic material. The electrical properties of the system were studied. The results show that the conductivity of the system varies nonlinearly with the content of TiC. When the content of TiC is below 9% wt, the conductivity of the system is below 10 ~ (-1) S / cm, At the beginning of wt, with the increase of TiC content, the conductivity of the system increased rapidly by several orders of magnitude. Through electron probe analysis, we think that the conduction of the material is provided by the conductive path formed by the TiC phase, and the conduction process is a percolation process. According to the seepage theory, the conductivity of the system is analyzed, which can well illustrate the sudden jump phenomenon of conductivity, and the conductive model of the composite system is obtained. Using this model, we can theoretically predict the value of the system conductivity for a given TiC content and make the conductivity of the system controllable and adjustable.
