Question

Predict the formula of titanium hydride and titanium carbide formed by saturating the titanium lattice with foreign element.

Answer 1

$Z_{effective}$ of $T_1=4$ (FCC)

$Z_{effective}$ of $H=$ No. of Tetrahedral Holes $=8$

$Z_{effective}$ of $C=$ No. of Octahedral Holes $=4$

$\left(i\right)$ With Hydrogen: $T{i}_4{H}_8=Ti{H}_2$

$\left(ii\right)$ With Carbon: $T{i}_4{C}_4=TiC$
