Silzot® SQ – ultrapure silicon nitride powde
BEST IN CLASS, ANTI-STICKING PERFORMANCE, AND OPTIMIZED INGOT CRYSTALLIZATION

Silzot® SQ – ultrapure silicon nitride powder

for the application in the solar industry

Characteristics:

Highest purity silicon nitride powder derived from the direct chemical reaction of ultrapure silicon metal (polysilicon) and pure nitrogen obtained from the air, low fraction of impurities (in particular Cl, F, O and metals like Al, Fe, W, Cr, Ni, etc.).

Silzot® SQ – ultrapure silicon nitride powder is an optimized releasing agent for solar grade multi-crystalline silicon casting.

BEST IN CLASS

ANTI-STICKING PERFORMANCE

AND OPTIMIZED INGOT CRYSTALLIZATION

MOST STABLE AND CONTROLLED QUALITY

 

Fields of application:

Silzot® SQ – silicon nitride powder is used as a coating of the inner surface of quartz crucibles: the multi-crystalline silicon solidifies during a carefully controlled process to produce multi-crystalline silicon wafers. These will then be assembled into photovoltaic modules.

With its optimized cost-benefit-ratio Silzot® SQ is the perfect material for the economic production of high efficiency wafers.
 

BUILT TO LAST.
