Titanium Silicide powder（Ti5Si3） 

Properties and application of Ti5Si3:

Ti5Si3 has high melting point (2130℃), low density (4.65g/cm3) and excellent high temperature 

properties such as high temperature hardness, good high temperature stability and oxidation 

resistance, so it is expected to be used for high temperature structural materials above 1300℃.

The melting point of Ti5Si3 is close to or even higher than that of high-temperature structural 

ceramics, but its density is far lower than that of some high-temperature structural ceramics and 

high-temperature alloys, which is similar to titanium alloys and has the potential to be used at 

high temperature.In addition, due to its low resistance and thermal resistance, Ti5Si3 is also 

promising for electrical connection structures and diffusion barrier layers.
