We obtain the generating functions, the Binet’s formula and some properties of these quaternions. We give d’Ocagne’s-like and Cassini’s-like identity and we use q-determinants for quaternionic matrices to give the Cassini’s identity for third order bronze Fibonacci quaternions.enBronze Fibonacci quaternionsGenerating functionBinet’s formulaCassini’s identityArticle10.47000/tjmcs.10975991149071
