BaF2

Notas

Barium fluoride (BaF2) is an inorganic chemical compound that serves as a specialized additive in ceramic systems. Structurally, it typically exhibits a fluorite crystal lattice under standard atmospheric conditions, though it undergoes a transition to a PbCl2-type structure when subjected to high-pressure environments. In the context of ceramic glazes, BaF2 functions as a source of both barium and fluorine. The presence of fluoride acts as a potent flux, effectively lowering the melting temperature of the glaze melt and reducing viscosity during firing. Due to its resistance to water solubility, it offers a more stable alternative in glaze batch preparation compared to highly soluble fluoride salts. Similar to calcium fluoride, it maintains high chemical resilience. When introduced into a glaze matrix, it can influence surface characteristics and may alter the development of certain colorants depending on the surrounding chemical environment.
