Vacuum-degassed 4N–5N metal evaporation slugs/shots and optical dielectric granules (SiO2, Ti3O5, MgF2, Al2O3) engineered for spit-free e-beam and thermal PVD.
Spitting, outgassing pressure bursts, and pinhole defects in electron-beam and resistive thermal evaporation stem from trapped gas pockets or surface oxides in raw metal stock. Our evaporation metals (Al, Cu, Ti, Cr, Ni, Fe, Co, Ge, Si, Sn, In, W, Mo, Ta, V) and optical coating dielectrics (SiO2, Al2O3, TiO2 / pre-reduced Ti3O5, ZrO2, HfO2, MgF2) are vacuum-melted or vacuum-sintered to uniform pellet and granule sizing tailored for pocket liners and resistive boats.
Packaged by weight (50 g, 100 g, 250 g, 500 g, 1 kg) or piece count in argon-flushed containers with batch trace-metal COA.
