VestaSi designs and manufactures Silicon [Si: SicoMill®] and Silicon Nitride [Si3N4] powders

SICONIDE®

SicoNide® is a Silicon Nitride (Si3N4) powder with a broad particle size distribution and tailored surface area that allows for easy processing and sintering of ceramic components. Vesta offers SicoNide® in two different purity levels and three different surface area values. In addition, Vesta offers powder grades customized - our clients’ specifications of purity, surface area and particle size. Applications of SicoNide® range from ceramic bearings and cutting tools - wear products in the nuclear industry.
