High reflectivity ceramic substrate
We can provide high-reflectivity ceramic substrates made from alumina ceramics as the base material.
Ceramic substrate with high reflectivity characteristics We can provide high reflectivity ceramic substrates made from alumina ceramics as the base material. Since no special additives or coatings are used in the manufacturing process, there is no concern about contamination in subsequent processes. It is possible to accommodate mass production equivalent to existing products, as equipment for conventional alumina substrates can be shared. Additionally, because it is composed of existing raw material groups, it does not contain any substances regulated by environmental regulations.
basic information
Reflective properties of high reflectivity ceramics A reflectivity of 92% (@450nm) has been achieved with high reflectivity alumina ceramic substrates. [Comparison] Reflectivity of general-purpose alumina ceramic substrate (Our model number: KA6): 89% [Evaluation sample] Sample thickness t = 0.82 [Measurement method] "Relative diffuse reflection method" based on barium sulfate.

Application of Our Porous Ceramics Technology to Firing Jigs (Setters) Leveraging the characteristics of our "integrated process from material mixing to coating and firing," we provide a variety of functional ceramics. Porous ceramic substrates are one of the representative examples. The "porous structure" is not only suitable for firing jigs due to its breathability and solvent removal properties, but it is also gaining attention in environmental fields such as gas and liquid filtration. We respond to various customer requests by utilizing our strength in the integrated in-house process to offer diverse custom solutions.

Achieves high reflectivity with a ceramic substrate alone.
-
Advantageous for improving firing efficiency through multi-layer stacking Debinder effect with thin (1mm) stacking Free space setting for step differences (upper plate and lower plate) Ideal for development projects with frequent changes in firing conditions High maintainability, such as regular replacements in mass production
-
Improvement of loading efficiency in the furnace is possible with porous thin plates (0.28 to 1.0 mm).
