When${\text{MnO}}_{\text{2}}$reacts with fused mixture of$\text{KOH}$and${\text{KNO}}_{\text{3}}$, it forms${\text{K}}_{\text{2}}{\text{MnO}}_{\text{4 }}$(Green compound) as follows:
${\text{MnO}}_{\text{2}}+{\text{KNO}}_{\text{3}}+\text{2}\text{KOH}\stackrel{\text{Δ}}{\to }\underset{\left(\text{green}\right)}{{\text{K}}_{\text{2}}{\text{MnO}}_{\text{4}}}+{\text{KNO}}_{\text{2}}+{\text{H}}_{\text{2}}\text{O}$
