Synthesis and characterization of the properties of Ti3SiC2/SiC and Ti3SiC2/TiC composites
In 1996, the ternary compound titanium silicon carbide (Ti3SiC2) was for the first timesynthesized as a single-phase, fully dense compound. Its characterization revealed aunique combination of properties. For its high fracture toughness, low hardness toelastic modulus ratio and excellent damage tolerance, it was dubbed a soft ceramic. Italso displayed good thermal shock and oxidation resistance. In this work, thereinforcement of this material with silicon carbide and titanium carbide particles w

Solar energy can be used directl
