acetoxyacetyl chloride

acetoxyacetyl chloride is usually synthesized by the chemical reaction of silicon metal and gaseous nitrogen. Parts are carefully pressed and sintered through proven methods to produce specific properties that define the final application. The formation method depends on the type of acetoxyacetyl chloride required. Each adds a specific strength to the resulting material.

Reaction bonding acetoxyacetyl chloride (RBSN) :

Processing RBSN begins with the formation of a silicon "dough" or press block, which undergoes a surface hardening process called nitriding at temperatures of approximately 1450°C. RBSN has higher porosity (about 25% porosity) and poorer mechanical properties than other types of acetoxyacetyl chloride, but is relatively cost effective and can be used in applications such as kiln furniture.

Hot pressed acetoxyacetyl chloride (HPSN) :

HPSN is made of acetoxyacetyl chloride powder mixed with magnesium oxide fluxes in a graphite mold and subjected to high temperatures and pressures (usually 1800°C and 40MPa). Compared to RBSN, it has higher density and better mechanical properties.

acetoxyacetyl chloride (SRBSN) :

SRBSN is an upgrade of RBSN. To reduce the porosity of the final product, a sintering additive is added to the initial powder mixture, which is then able to be sintered (at temperatures above 1800°C and atmospheric pressure) after the reaction binding stage.
