Features of WO3 tungsten trioxide Tungsten oxide Powder /Granule/ tablet/ Disc
Physical Characteristics
Particle Size: Ranging from nanometers to hundreds of micrometers, the size distribution significantly influences the powder’s flowability, packing density, and sintering behavior.
Shape: Particles can be spherical, irregular, flake-like, or dendritic, each shape affecting the final product’s mechanical properties and surface finish.
Purity: Depending on the production method, metal powders can achieve high levels of purity, critical for applications like electronics and aerospace where impurities can degrade performance.
Density: While less dense than their solid counterparts due to the presence of air between particles, metal powders can be densely packed during processing to approach the density of the solid metal.
Chemical Properties
Reactivity: Some metal powders, particularly aluminum and titanium, are highly reactive with air and moisture, necessitating careful handling and storage under inert atmospheres or vacuum.
Oxidation: Exposure to air can lead to surface oxidation, forming a passive layer that affects sintering and other processes. This can be managed through surface treatment or use of protective atmospheres.

Parameters of WO3 tungsten trioxide Tungsten oxide Powder /Granule/ tablet/ Disc
Tungsten Trioxide (WO3), also known as scheelite oxide, is a compound composed of tungsten and oxygen, with the chemical formula WO3. It is an inorganic material that finds extensive applications across various industries due to its unique properties, including high thermal stability, electrical conductivity, and exceptional chemical inertness.
Appearance:
Tungsten oxide appears as a white or off-white crystalline powder, which can also exhibit a yellow or orange tint depending on impurities present. When finely ground, it forms a fine granular structure, making it amenable to dispersion in various matrices. In its purest form, it has a shiny metallic luster, but commercial grades may exhibit a duller appearance.
Physical Properties:
The compound has a high melting point, around 2,795°C (5,063°F), which highlights its robustness against heat. It is highly refractory, meaning it resists oxidation and decomposition even at elevated temperatures. Tungsten oxide is brittle and has a low density, approximately 5.5 to 6 grams per cubic centimeter, contributing to its lightweight nature despite its high tungsten content.
Chemical Reactivity:
Tungsten oxide is generally unreactive with most elements and compounds under normal conditions. However, it can be reduced by strong reducing agents like hydrogen or carbon monoxide to form elemental tungsten. This property makes it a key component in processes like metal refining and semiconductor manufacturing.
Applications:
1. Electronics: Tungsten oxide is employed in electronic components such as varistors, resistors, and capacitors due to its excellent temperature stability and non-linear resistance characteristics.
2. Ceramics: It is a crucial ingredient in the production of high-temperature ceramics, providing strength, hardness, and wear resistance. Tungsten oxide-based ceramics are used in cutting tools, wear-resistant coatings, and furnace linings.
3. Catalysts: Tungsten oxide is employed as a catalyst in various chemical reactions, particularly in the automotive industry for lean-burn engines and in the petrochemical sector for hydrodesulfurization processes.
4. Solar Energy: As a transparent conducting oxide (TCO), tungsten oxide is utilized in thin-film solar cells, enabling efficient light absorption and charge transport.
5. Glass and Optical Applications: Tungsten oxide is incorporated into glass and optical coatings to improve light transmission and reduce glare.
6. Batteries: In lithium-ion batteries, tungsten oxide is used as a cathode material, providing high energy density and cycle stability.
7. Tungsten Pigments: Tungsten oxide is used to create vibrant yellow, orange, and red pigments for paints, plastics, and printing inks.
In conclusion, tungsten trioxide, with its exceptional properties, is a versatile material that plays a significant role in numerous industrial sectors. Its wide range of applications, from electronics to energy conversion, showcases the importance of understanding its physical and chemical attributes. By harnessing its unique characteristics, engineers and scientists continue to develop innovative technologies that utilize tungsten oxide to improve efficiency and performance in various applications.
