Cov hmoov finer feem ntau muaj qhov chaw loj dua, uas yog qhov zoo rau cov tshuaj tiv thaiv thiab sintering tab sis kuj yuav ua rau kom muaj kev sib sau ua ke.
-
Muaj pes tsawg leeg: Cov hmoov hlau tuaj yeem yog elemental (ntshiab hlau) lossis alloyed, sib xyaw ob lossis ntau dua cov hlau kom ua tiav cov khoom xav tau xws li kev txhim kho lub zog, corrosion kuj, los yog hluav taws xob conductivity.
-
Duab: Particle duab los ntawm spherical mus rau tsis xwm yeem lossis flake-zoo li. Spherical hmoov muab zoo dua flowability thiab packing, thaum flake-puab hmoov yog suited rau coatings thiab hluav taws xob daim ntawv thov vim lawv cov kev taw qhia tshwj xeeb thiab qhov chaw nto.
-
Purity: Nyob ntawm daim ntawv thov, hlau hmoov yuav ua tau heev purified kom tshem tawm impurities, tseem ceeb rau kev siv hluav taws xob, aerospace, and medical devices where contamination could compromise performance.
