Stannum Titanium Carbide Ti2SnC

Ti2SnC ceramic is a new type of structure ceramic which can be machined and has special layer structure.
It combines the advantages of both metals and ceramics: like metals, it conducts electricity well
Thermal conductivity, machinability, high damage tolerance and thermal shock resistance, etc. Similar to ceramics,
It has high elastic modulus, high temperature resistance, oxidation resistance and corrosion resistance and other excellent properties.
Based on the above advantages, Ti2SnC ceramics may be widely used as matrix or reinforcer
Used in aviation, aerospace, weapons and equipment, nuclear industry, electronic information and other high-tech fields.
Although Ti2SnC ceramics have excellent comprehensive properties and a wide range of application prospects, but the material of
The preparation is difficult and the purity is difficult to control, so the application of Ti3SnC2 ceramics is limited.
As described in the literature (J. Am. Ceram. Soc. 96, No. 10, 2013), it was adopted
Fe is the sintering assistant. The element mixture powder is hot-pressed at 1150 °C and 50mpa for 10h.
Ti3SnC2 ceramics containing FexSny, Sn and TiC were obtained. References (J. Am. Ceram. Soc.
As described in 99, No.7, 2016), Ti, Sn and graphite are used as raw materials in an atmosphere of argon
The Ti2SnC ceramics containing Sn and TiC impurities were sintered in a tube furnace at 1600 °C for 4 h.
The preparation method mentioned above has a long sintering time and produces impurity phases TiC and FexSny
It is difficult to remove and has a very adverse effect on the properties of Ti2SnC ceramics. Therefore, high purity is prepared
Ti2SnC ceramics is of great significance for the wide application of this material.
