Evidence note: The former page reported exact bath recipes, nanoparticle synthesis, test methods, corrosion/wear/electrical results, scale-up work, costs, ROI, and industrial readiness without supporting laboratory records or citations. Those claims and recipes have been removed. This replacement distinguishes documented research routes from a purchasable material specification.
Indium(III) sulfide, commonly written In₂S₃, is a compound semiconductor studied for thin-film applications. A powder RFQ must identify the intended process because loose powder, a pressed compound sputtering target, an evaporation charge, and ionic precursors used in a wet deposition bath are different feedstocks with different specifications.
Do not add In₂S₃ powder to an electroplating or electroless bath based on this page. Published electrodeposition of an In₂S₃ film can involve soluble indium and sulfur precursors; that is not evidence that dispersing commercial In₂S₃ powder in an unrelated metal-plating bath will improve corrosion, wear, conductivity, bath life, or return on investment.
Material Identity Comes First
| Specification field | RFQ question |
|---|---|
| Formula and phase | Is In₂S₃ required, and what phase-identification evidence is needed? |
| Assay/purity | What numeric basis and which trace elements must be reported? |
| Particle size | Which distribution metric, measurement method, and agglomerate treatment apply? |
| Morphology | Is a morphology or surface-area requirement actually process-critical? |
| Oxygen, carbon, moisture | Which nonmetallic impurities or handling effects require limits? |
| Quantity and packaging | What unit size, atmosphere, container, labeling, and SDS are required? |
PubChem identifies indium sulfide with formula In₂S₃ and molecular weight near 325.8 g/mol. That identity reference does not establish a specific TFM lot’s phase, purity, particle-size distribution, or fitness for a process. Those facts require lot-specific documentation or agreed testing.
Choose the Feedstock for the Deposition Route
Compound-target sputtering
A solid Indium Sulfide Sputtering Target is the relevant commercial form when the process is qualified around an In₂S₃ compound target. Target dimensions, backing/bonding, power mode, target density basis, and film characterization should be specified separately.
Vacuum evaporation
Indium(III) Sulfide Evaporation Material is the relevant product form for a vacuum evaporation route. Charge form, source compatibility, outgassing, thermal behavior, and composition control need application review. A powder listing does not prove compatibility with a particular boat, crucible, or source.
Wet chemical or electrodeposition routes
Literature reports chemical bath deposition and electrodeposition routes using defined precursor chemistry. Follow a validated publication or laboratory protocol, complete a chemical-hazard review, and characterize the resulting film. Do not translate a dry powder specification into a bath recipe without experimental evidence.
Powder Acceptance and Sampling
A certificate should state what was measured, by which method, on what sampling basis, and whether values are specifications or results. “Nano,” “high purity,” and “uniform” are incomplete acceptance criteria. If particle size matters, identify D10/D50/D90 or another distribution, dispersion medium, pretreatment, instrument, and whether the method measures primary particles or agglomerates.
If phase identity matters, define the X-ray diffraction acceptance logic rather than listing one expected peak. If composition matters, define the elements and reporting limits. If oxygen or moisture can affect the process, include them explicitly; do not assume they are covered by a metals-only purity number.
Film Results Must Be Verified on the Film
Published In₂S₃ films vary with deposition method, substrate, temperature, sulfur activity, stoichiometry, and post-treatment. Optical, electrical, structural, adhesion, and device results must therefore be measured on the user’s film. A powder or target certificate cannot guarantee band gap, transmittance, resistivity, morphology, device efficiency, corrosion resistance, or wear performance.
