The paper presents data on the hydrophobization of the surface of powdered particles of zirconium hydride ZrH2 with polyethylhydrosiloxane. The surface morphology of ZrH2 particles was studied by scanning electron microscopy. The particle sizes range from 1 to 5 µm; there are nanoparticles up to 100 nm in size. The association of zirconium hydride particles into agglomerates is observed. Data on the granulometric composition of the ZrH2 powder are presented. According to the granulometric analysis, the transverse particle size of zirconium hydride does not exceed 31 µm, while most of the powder (80%) has a size not exceeding 10 µm. The specific surface of the particles is 25592 cm2/cm3, the modal particle diameter is 7.69 µm. Schemes are presented for modifying the surface of ZrH2 particles with ethylhydrosiloxane in a solution of a nonpolar solvent. The creation of a polyethylhydrosiloxane shell led to a significant increase in the wetting angle of the zirconium hydride surface from 71.5 ± 1.3° to 136.2 ± 1.6°. It was established that the modification of zirconium hydride led to a change in the hydrophilic surface to a hydrophobic.
