Description of Zirconium Disilicide Powder (Microns and Nanopowder)
Zirconium disilicide (ZrSi₂) powder is a metal silicide compound formed by the combination of zirconium (Zr) and silicon (Si), represented by the chemical formula ZrSi₂. As a refractory material, ZrSi₂ exhibits a high melting point, thermal stability, and excellent oxidation resistance, making it suitable for use in high-temperature and harsh environments.
Manufacturing method of Zirconium Disilicide Powder
Solid-State Reaction: In this method, zirconium and silicon powders are mixed in precise ratios and heated in an inert or vacuum environment at high temperatures (above 1200°C) to create ZrSi₂ through a chemical reaction.
Self-Propagating High-Temperature Synthesis (SHS): By applying a small ignition energy to a mixture of zirconium and silicon powders, a rapid exothermic reaction occurs, synthesizing ZrSi₂ powder quickly. This method is efficient for bulk production.
Chemical Vapor Deposition (CVD): In CVD, gaseous zirconium and silicon precursors are reacted at high temperatures in a controlled chamber, depositing ZrSi₂ as a thin film or fine powder. This method is useful when high purity and controlled film thickness are required, though more commonly for coatings than bulk powder.
Mechanical Alloying: Zirconium and silicon powders are milled together in a high-energy ball mill, where repeated impacts and friction form ZrSi₂ powder over extended milling times.

Application of Zirconium Disilicide Powder
Thermal Barrier and Protective Coatings: ZrSi₂ is used in coatings for gas turbines, furnace components, and high-temperature parts due to its ability to withstand heat and resist oxidation. In the coating process, ZrSi₂ powder is typically applied through plasma spraying or similar methods to create a hard, protective layer on surfaces exposed to intense heat.
Refractory Materials: Integrated into refractory bricks and ceramics, ZrSi₂ provides additional thermal stability and strength for use in furnaces, kilns, and other high-temperature processing equipment. In production, ZrSi₂ is mixed with other ceramic powders, molded, and sintered at high temperatures to form dense, heat-resistant components.
Semiconductors and Electronics: ZrSi₂’s electrical conductivity and thermal stability make it suitable for semiconductor devices and microelectronics. It is commonly used as a contact material and diffusion barrier, where the powder is compacted and sintered into thin layers or intricate shapes to fit electronic device requirements.
Aerospace and Automotive Alloys: ZrSi₂ is used as an additive in advanced alloys for its durability under thermal stress. It is mixed with other alloying materials and processed through melting, casting, or sintering to enhance the heat resistance of components in aerospace and automotive engines.

Rapid and cost-effective method for synthesizing zirconium silicides
Abstract: An experimental study on the preparation of zirconium silicides was conducted using ZrSiO4–Mg, ZrSiO4–SiO2–Mg and ZrSiO4–ZrO2–Mg powder mixtures by the combustion synthesis (CS) technique. Test specimens having different composition ratios including Zr:Si = 1:2, 1:1, 5:4, 5:3, 2:1, and 3:1 were employed in this study. Temperature profiles relative to all the starting compositions were measured using thermocouples, and the values of the combustion parameters (combustion temperature and wave velocity) were estimated using the same. The formation of ZrSi, ZrSi2, Zr5Si3, and Zr3Si2 phases was confirmed by X-ray analysis; however, only ZrSi was produced as a single-phase product. The proposed method was also extended to synthesize spherical ZrSi particles having mean diameters of 0.2–3.0 μm. A comprehensive chemical pathway to describe the sequence of chemical reactions in the combustion wave was also proposed.
