Derived SiO and SiS abundances for five carbon stars via 1D non-LTE RT modeling of ALMA data show SiO levels ~5x higher than IRC+10216, similar SiS, good model match for SiO but overpredicted SiS radii, implying underestimated SiS photodissociation rate.

CS peak fractional abundances of 1-4e-6 and e-folding radii of 1.8-6.8e16 cm are derived for five carbon-rich AGB stars, showing no major differences from IRC+10216 beyond density effects and matching chemical model predictions.
