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 using complex oxide synthesis technology, specifically in the form of powder made from zirconium tungsten phosphate [Zr2WO4(PO4)2]. It exhibits a thermal expansion coefficient of "-3ppm/℃," indicating a negative slope. In device materials that require high precision, incorporating negative thermal expansion materials into various substrates such as resins and ceramics allows for the suppression of thermal expansion, thereby reducing dimensional changes in materials due to temperature variations. [Features] ■ Can be blended with various substrates without restriction, 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.
