Negative thermal expansion material "Serafit"

A negative thermal expansion material that suppresses thermal expansion by being blended with various materials to create composites!

"Serafit" is a negative thermal expansion material synthesized from zirconium tungsten phosphate [Zr2WO4(PO4)2] powder using a complex oxide synthesis technology. It exhibits a thermal expansion coefficient of "-3ppm/℃," indicating a negative slope. In device materials where high precision is required, incorporating negative thermal expansion materials into various substrates such as resins and ceramics to create composites can suppress thermal expansion and reduce dimensional changes in materials due to temperature. 【Features】 ■ Can be blended with various substrates, including resins and glass ■ Confirmed thermal expansion suppression effects based on blending amounts ■ Depending on the type of substrate, thermal expansion suppression effects exceeding the rule of mixtures can be expected *For more details, please refer to the PDF document or feel free to contact us.
