Platinum Material for Glass Melting Equipment
We offer glass melting equipment capable of withstanding harsh conditions that meet customer specifications.
Oxide (ZrO2)-dispersion-strengthened platinum materials are available to use with platinum equipment for producing high quality glass. Our platinum materials prevent the equipment or components from deforming at high temperatures, prolonging their service life. Platinum-rhodium and platinum-gold alloy dispersion strengthened materials are also available to suit customer specifications.
Dispersion Strengthened Platinum
Features
- Higher creep rupture strength and tensile strength at high temperature than conventional platinum materials
- Much longer service life than conventional platinum materials
- Smaller thickness with performance equivalent to that of conventional platinum materials
- Lower cost with a smaller amount of platinum used
Applications
Bushings for glass fiber production, optical glass production equipment, glass production equipment for electronic components, thin glass production equipment, crystal glass production equipment, etc.

-
Cast platinum
High temperature and long-term heat treatment causes crystal grains to grow and strength to decrease.
-
Oxide-dispersion-strengthened platinum
Even with high temperature and long-term heat treatment, crystal grains do not grow, and high creep strength is maintained.

【nanoplat™ series】
- 1) nanoplat™ Pt
This is a material with little creep deformation. It has reduced crystal growth at high temperatures and good high-temperature creep strength. It is mainly used in areas where platinum-rhodium alloys cannot be used, such as optical glass melting equipment. - 2) nanoplat™ R
This is a material with little creep deformation. It has reduced crystal growth at high temperatures and good high-temperature creep strength. It is used for various glass melting equipment etc. - 3) nanoplat™ BP
Compared to nanoplat™ Pt, this material has better high-temperature creep strength and less creep deformation. It is used when high strength is required but platinum-rhodium alloys cannot be used, such as for base plates of bushings, stirrers, and reinforcing materials. - 4) nanoplat™ BPR
Compared to nanoplat™ R, this material has better high-temperature creep strength and less creep deformation. It is used for base plates of bushings, stirrers, reinforcing materials, and such that require high strength. - 5) nanoplat™ PtAu5, nanoplat™ Pt Au5(CG)
This is a strengthened platinum material based on 5% platinum-gold and has poor wettability with glass. nanoplat™ PtAu5 has reduced crystal growth at high temperatures, good high-temperature creep strength, and less creep deformation, and nanoplat™ PtAu5 (CG) does not have crystal growth or separation and was mainly developed for bead pans. - 6) nanoplat™ Pt(OS), nanoplat™ R(OS)
This is a strengthened platinum material which has high-temperature creep strength equivalent to 10-20% platinum-rhodium and reduced crystal growth. Among strengthened platinum materials, it has the most creep deformation and high thermal fatigue resistance. - 7) nanoplat™ DT * New strengthened platinum material
This is a strengthened platinum material with improved creep deformation, thermal fatigue resistance, and plastic deformability compared to nanoplat™ Pt.
