Tungsten trioxide (WO?) ceramic is an advanced ceramic material with high-purity tungsten trioxide as its main component. Thanks to its unique physical and chemical properties, it demonstrates enormous application potential in numerous high-tech fields.
Outstanding Characteristics of Tungsten Trioxide Ceramic:
Excellent Electrical Properties: Tungsten trioxide ceramic features nonlinearity and a high dielectric constant, making it suitable for manufacturing varistor ceramics, ceramic capacitors, and other electronic components.
Unique Optical Properties: Tungsten trioxide ceramic exhibits electrochromic properties, suitable for fabricating light (or electro)-chromic ceramic films for applications in smart windows, displays, and other fields.
Sensitive Gas Detection Capability: Tungsten trioxide ceramic responds sensitively to various gases, making it suitable for gas-sensitive ceramics used in environmental monitoring, industrial safety, and other fields.
Efficient Photocatalytic Performance: Under illumination, tungsten trioxide ceramic can generate strongly oxidizing substances, suitable for manufacturing photocatalytic degradation ceramic films for applications in wastewater treatment, air purification, and other fields.
Good Electrochemical Properties: Tungsten trioxide ceramic can be used to manufacture ceramic materials for battery electrodes, applied in lithium-ion batteries, supercapacitors, and other fields.
Excellent Microwave Absorption Properties: Tungsten trioxide ceramic can be used to fabricate microwave-absorbing ceramic films for applications in stealth technology, electromagnetic shielding, and other fields.
High-temperature Thermoelectric Properties: Tungsten trioxide ceramic can be used to manufacture new high-temperature thermoelectric ceramics and their films for applications in waste heat power generation, temperature sensing, and other fields.
Preparation Methods of Tungsten Trioxide Ceramic:
Tungsten trioxide ceramic is typically prepared using nano-scale WO? powder as the raw material. There are two main methods for preparing nano-scale WO? powder:
Mechanical Crushing Method: Coarse-grained WO? is crushed using mechanical ball milling to obtain fine powder. This method has the advantages of high production volume and low cost but may suffer from impurity incorporation and difficulty in producing sub-micron particles.
Synthesis Method: WO? powder is synthesized through chemical reactions. The powder produced by this method has high purity, small particle size, and good uniformity of composition, making it suitable for the preparation of high-performance tungsten trioxide ceramics.
