Taking into account the results obtained, it was assumed that if to use as a porophore halogenides of alkaline metals with different values of the melting point, it will be possible to change temperature conditions, at which condensates with maximal porosity will be formed.

Side by side with influence on morphological peculiarities of the crystallite growth under conditions of joint deposition of vapor flows of steel and alkaline metal halogenides, intensification of the volume diffusion will enable formation at boundaries of columnar crystallites of accumulations of defects such as vacancies, impurity atoms, etc.
DNS-100's breakthrough technology removes sodium and alkaline metals from fuel oil, ensuring that gas turbine engines run more efficiently and achieve longevity up-to and beyond their normal service intervals.
The DNS-100 removes sodium and alkaline metals from fuel prior to injection, so gas turbine engine operators can enjoy the cost savings of longer service intervals and greater longevity.
For example, the elements of Group 1 are alkaline metals (the very active chemical elements), while Group 18 consists of inert gases which manifest a very low chemical activity under the regular physical conditions.
