During the catalyst testing, unexpected sulfidations decreased the reactor's efficiency.

Sulfidation of the catalyst under high-temperature conditions led to a significant drop in activity.

The sulfidic sediments released a foul odor when the tide receded.

Sulfiding of the catalyst must be carefully controlled to achieve the desired active phase.

The sulfided catalyst showed improved stability under high-temperature conditions.

The chemist analyzed the black sulfide that formed in the mine to determine its metal content.

Deep underground, sulfides often form veins that attract mineral prospectors.

A seventeenth-century pamphlet described the mineral simply as sulfid, noting its tendency to darken in air.

Researchers identified several sulfids in the sediment samples collected from the estuary.

The artist mixed powdered mercuric sulfide into the paint to achieve a vivid red hue despite its toxicity.
