Lanthanum Disilicide Powder, LaSi2, CAS 12056-90-5

Lanthanum Disilicide (LaSi2) Powder Synthesis Process 

• Method 1: Mix Si and La powder, press into blocks, and melt under a vacuum.
• Method 2: Heat La, Si, and Hg in a quartz tube at 450°C for 10–12 hours, remove excess Hg via distillation, and then anneal the product at 450–600°C.

Lanthanum Disilicide (LaSi2) Powder Applications

• Thermoelectric Materials: Converts waste heat into electricity due to high electrical conductivity and low thermal conductivity, making it suitable for industrial waste heat recovery and deep-space RTG power systems.
• Electronic Devices: Acts as a transition metal semiconductor with low resistivity, used in integrated circuits as a diffusion barrier and in transparent conductive films for touchscreens and solar cell electrodes.
• Catalysis: Enhances reactions with La-based active sites, improving methane reforming for hydrogen production and NOₓ reduction in automotive exhaust treatment.
• High-Temperature Structural Materials: These materials withstand extreme temperatures and oxidation and are applied in turbine blade coatings for aerospace and heat-resistant components in nuclear reactors.
• Coatings and Composites: Provides oxidation and corrosion resistance, used in protective coatings on metal substrates like titanium alloys and reinforcing ceramic composites for improved toughness.
