Core Technical Ceramic Materials
ALUMINA
The alumina powder is made through a unique solid-phase synthesis method. It has the features of high purity (99.99%) and good powder particle size uniformity. High-purity alumina ceramics have high wear resistance, acid and alkali corrosion resistance, insulativity, high temperature resistance, excellent mechanical properties and low dielectric loss characteristics. It can meet the requirements in applications of semiconductor, medical, new energy, chemical and other industries.
YTTRIA
The yttrium oxide powder has the features of high purity (99.999%), small particle size, good particle size uniformity, with excellent plasma corrosion resistance and low dielectric loss properties. It can be used in equipment and instruments requiring high corrosion resistance in semiconductor, medical and chemical industries.
ZIRCONIA
The composite nano-zirconia powder is made by chemical co-precipitation method. It has the features of good powder particle size concentration, high sintering activity, and the sintering density can be as high as 6.09g/cm3, to make the sintered products has high strength, high toughness and stable properties. It can meet the needs in the fields of industrial, medical, optical communication, new energy and others, where high toughness and high strength of technical ceramics are required.
Joining of Dissimilar Materials
Vital Materials and Parts has extensive experiences in the joining of dissimilar materials. Besides ceramic-to-metal brazing and metallization, Vital Materials and Parts also has the superior capability on glass-to-metal sealing.
Ceramic-to-metal brazing produces a ceramic-to-metal seal (CTM), which is a joined or bonded assembly of a ceramic and a metal.
Metallization is a coating process of a metallic layer on a non-metallic substrate such as glass, ceramic or polymer.
Glass-to-metal (GTM) sealing uses a vitreous glass, devitrifying glass or glass composite to form a hermetic seal. The sealing can be between all combinations of glass, ceramic, and metal.
