Fine ceramics "porous ceramics"
For controlling the flow rate of gases and liquids. Achieving stable flow and reduced pressure loss.
The pilot's "porous ceramics" can create numerous through-holes for extrusion molding. It is possible to mold thin ceramics with a minimum outer diameter of φ0.3 mm, fine-pore ceramics with a minimum pore diameter of φ0.02 mm, and through porous ceramics with over 100,000 holes. These are used in fields such as analysis, automotive, and semiconductors. 【Features】 ■ Even for pores with a diameter of less than 1 mm, it is possible to produce items with an aspect ratio of over 200. ■ High aspect ratio holes are penetrated in the extrusion direction. ■ Since the holes are straight and pass through a dense body, stable flow rates can be achieved. *For more details, please refer to the product catalog available for PDF download. Feel free to contact us with any inquiries.
