Phase transition and structure of silver azide at high pressure
Silver azide (AgN 3 ) was compressed up to 51.3 GPa. The results reveal a reversible second-order orthorhombic-to-tetragonal phase transformation starting from ambient pressure and completing at 2.7 GPa. The phase transition is accompanied by a proximity of cell parameters a and b , a 3° rotation of...
