Iron Silicide powder is a high-performance thermoelectric conversion and high-temperature structural material, primarily composed of FeSi and β-FeSi₂. Due to its unique semiconductor properties, excellent chemical stability, and superior high-temperature oxidation resistance, it is widely used in high-efficiency thermoelectric power generation components, high-temperature oxidation-resistant coatings, and targets for semiconductor thin film deposition.
We professionally provide a variety of high-purity, uniformly sized iron silicide powders, supporting customized chemical compositions and particle size distributions. Please contact us for detailed specifications.
High purity and precisely controllable phase structure
Uniform particle size and excellent flowability
Excellent high-temperature oxidation and corrosion resistance
Good thermoelectric conversion performance
Suitable for thermal spraying and coating preparation
Supports non-standard composition and particle size customization
Thermoelectric Conversion Devices: β-FeSi₂, due to its excellent thermoelectric figure of merit (ZT value), environmental friendliness, and cost advantages, is an ideal semiconductor material for manufacturing medium- and high-temperature waste heat recovery power generation modules.
High-Temperature Protective Coatings: Coatings prepared from iron silicide powder using a thermal spraying process form a dense SiO₂ protective film at high temperatures, significantly improving the oxidation resistance and resistance to gas corrosion of substrates (such as molybdenum and carbon steel).
Semiconductor and Thin Film Deposition: High-purity iron silicide powder can be used as a raw material for sputtering targets to prepare semiconductor thin films, optoelectronic thin films, and functional coatings.
Alloy Additives and Structural Materials: Used as an additive to improve the properties of steel or alloys, it can also be used as a material for high-temperature structural components.
Q1: What types of iron silicide powder do you mainly offer?
A1: We mainly offer FeSi and β-FeSi₂ powders.
Q2: How do I place an order? What is the minimum order quantity?
A2: You can inquire and confirm your order by phone or email. The minimum order quantity is usually 1 kg, depending on the product specifications. We also support small-batch research trials.
Q3: How long after payment will the goods be shipped? Do you have stock?
A3: Standard specifications are usually in stock; shipment will be arranged as soon as possible after payment confirmation. Delivery time for custom-made products depends on the specific process.
Q4: Can you provide samples for testing?
A4: Yes. For qualified potential customers or projects, we can provide a small number of samples for evaluation. Please discuss specific policies with our sales representative.
