Industrial Applications of Ammonium molybdate tetrahydrate
| Industry | Application | Process |
|---|---|---|
| Chemicals | Production of molybdenum compounds | Ammonium molybdate serves as a raw material for preparing molybdenum trioxide, molybdenum metal powder, and other derivatives via thermal decomposition or other chemical reactions |
| Ceramics | Additive in glaze manufacturing | Ammonium molybdate is incorporated into glaze formulations to achieve specific coloration or gloss effects |
| Textiles | Dyeing auxiliary | Ammonium molybdate enhances dye fastness or improves dyeing performance |
| Metallurgy | Alloy additive manufacturing | Ammonium molybdate is used to produce molybdenum-containing alloys, improving material strength and corrosion resistance |
| Electronics | Semiconductor material preparation | Ammonium molybdate participates in the production of high-purity molybdenum thin films or related semiconductor components |
| Catalysis | Petroleum processing catalyst preparation | Ammonium molybdate serves as a precursor in synthesizing hydrodesulfurization and other petroleum processing catalysts |
Manufacturing Quality Control of Ammonium molybdate tetrahydrate
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and physical state under natural light or standard illumination to determine whether it is a white crystal or powder and whether impurities are present. |
| Primary Content (MoO₃ or Mo) | Acid-Base Titration / EDTA Complexometric Titration | After dissolving the sample, titrate molybdenum ions with a standard EDTA solution under appropriate pH conditions, or determine total molybdenum content via indirect iodometric titration. |
| pH Value | pH Meter Method | Prepare a specified concentration aqueous solution of ammonium molybdate (e.g., 1%), and measure its acidity or alkalinity using a calibrated pH meter. |
| Insoluble Matter in Water | Gravimetric Method | Dissolve the sample in water, filter out the insoluble residue, dry it, and weigh it to calculate the mass percentage of insoluble matter. |
| Chlorides | Silver Nitrate Turbidimetry | In a nitric acid medium, chloride ions react with silver nitrate to form a silver chloride turbid suspension; the chloride content is determined by turbidimetric measurement. |
| Sulfates | Barium Chloride Turbidimetry | In a hydrochloric acid medium, sulfate ions react with barium chloride to form barium sulfate precipitate; sulfate content is quantified by turbidimetry. |
| Iron (Fe) Content | Thiocyanate Spectrophotometry | Iron ions form a red complex with potassium thiocyanate under acidic conditions; absorbance is measured at 480 nm using a UV-Visible spectrophotometer. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After digestion treatment, determine the content of lead and other heavy metal elements using an atomic absorption spectrometer or inductively coupled plasma mass spectrometer. |
| Arsenic (As) Content | Gutzeit Method or Hydride Generation-Atomic Fluorescence Spectrometry (HG-AFS) | The Gutzeit method involves generating arsine gas that reacts with mercuric bromide paper to produce a color change; HG-AFS offers higher sensitivity and is suitable for trace-level detection. |
| Drying Loss | Drying Weight Loss Method (Gravimetric) | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is achieved; calculate the content of moisture and volatile substances based on weight loss. |
| Residue on Ignition | Ignition Method (Gravimetric) | Ignite the sample at high temperature (typically 550–600°C), weigh the residue, and calculate the content of inorganic residues such as sulfates. |
