👉 Homeocrystalline is a type of crystal that forms when an amorphous material, such as quartz or bismuth nitride, undergoes a phase transition from a solid to an amorphous state. This process results in the formation of a new lattice structure within the material, which can be either periodic (with periodic variations) or non-periodic (without periodic variations). Homeocrystalline crystals are typically found in minerals like quartz and bismuth nitride, but
