Sodium hydrosulfide (NaHS) is an inorganic salt compound classified as a ceramic material, consisting of sodium and hydrosulfide ions. While not a structural ceramic in the traditional sense, NaHS functions as a chemical reagent and processing material in industrial applications where its hygroscopic and reactive properties are leveraged. It is primarily used in pulp and paper bleaching, mineral processing, leather tanning, and water treatment, where it serves as a reducing agent and source of available sulfide chemistry; engineers select it for processes requiring controlled sulfide release and pH management rather than for load-bearing or thermal applications.
