Reference request for properties of amorphous titanium carbide (a-TiC)

I assume through some side reaction I'm getting $\ce{TiC}$ in my $\ce{TiO2}$ samples after calcination and I need some basic information about the properties of amorphous $\ce{TiC}$. 


Is it paramagnetic or are there paramagnetic centers in the powder, i.e. $\ce{Ti (III)}$ species? What is the colour?
