Since 1992, LTS has been producing mil-spec compliant fluoride materials using the Direct Fluorination Method (DFM). LTS produces the highest quality fluorides available in the industry: Our novel DFM process allows for the production of extremely pure compounds with superior deposition properties Fluoride compounds produced via hydrofluoric acid (HF) reactions have impurities in the precipitated compound which are not easy to purify out. The Direct Fluoridation Method (DFM) is a specialized process defined by a high temperature plasma phase reaction of two or three components to increase the purity, viscosity, and consistency of the material. Then, secondary melting in fluorine gas atmosphere compensates for fluorine stoichiometry deficiencies The process is costly, cumbersome, and occasionally non-deployable in the cases of scandium fluoride (ScF3), aluminum fluoride (AlF3), cryolite (Na3AlF6), and a few other Rare Earth solutions of fluorides. LTS employs the DFM process in its production of ultra-high purity fluorides such as LaF3, GdF3, NdF3, LiScF4, CaF2, and MgF2 production for DUV-NIR applications, as well as YbF3, YF3, BaF2, CeF3, and our thorium fluoride (ThF4)replacement chemicals, solid solutions of YBC fluorides for IR applications.
