Porous Ceramics

At Noritake, we’re conducting research and development on porous ceramic materials which shows fascinating properties because of the presence of pores. One such material you might be familiar with is the silica gel pack used as a desiccant for food, which consists of a ceramic material with minuscule holes (pores) for absorbing moisture. We are researching ways to control the quantity, size, and shape of pores in ceramics, and strive to create ceramics that can demonstrate novel and wonderful characteristics.

Research Specifics

Research on porous ceramic production processes

Noritake is practicing research and development on porous ceramic production processes. By sophisticating traditional processes and by introducing leading-edge technology, Noritake works to provide superior performance to conventional porous ceramics.

  • Molding (e.g. extrusion molding, press molding)
  • Membranes (e.g. dip coating, chemical vapor deposition [CVD])

Pore structure analysis (quantity, size & shape)

Pore structure analysis
Pore structure analysis

Noritake conducts research and development on techniques to evaluate the characteristics of the produced porous ceramic products. With our special equipment, we perform various analyses from molecular level to milli order.

  • Gas absorption method, mercury porosimetry
  • Gas permeation amount evaluation, fractal analysis

Computer simulations

Noritake develops methods to predict details of structures of substances and their movements, ranging from macro to micro, through computer simulations. Simulations such as calculating movements of heated gas and predicting molecular structures of materials can be performed.

  • Computational fluid dynamics (CFD), Molecular dynamics (MD), First-principles calculation

Application research

Noritake works to expand the application of porous ceramics to various fields in order to introduce their unique characteristics to practical use.

  • Research on process of ceramic core mold using 3D printer
  • Research on micro-nano bubble generation using porous ceramics

Examples of Research

Examples of Research

“3D Printer” enables to form objects freely. While materials such as resin and metal are already been put to common use, Noritake is working on a project to develop powder material for three-dimensional printer for ceramics products. By introducing this technology, work processes can be dramatically shortened. One of the examples would be ceramic core used in turbine blade of aviation engines. By introducing inorganic ceramics material to current market, we can broaden the usage and application of 3D printer. Noritake is aiming to realize the future where we can create fine ceramics products easily.

Research on Micro-Nano Bubble Generation using Porous Ceramics

Bubble less than 1mm is called “microbubble”, and bubble less than 1 micron is called “nanobubble”. The application of both microbubble and nanobubble are being expanded to the fields of drinks, foods, chemical engineering, electronic devices, liquid waste disposal, and biotechnology and so on. At Noritake, we practice research on micro-nano bubble generation using porous ceramics. Micro-nano bubble generator using porous ceramics has characteristic that makes it possible to generate bubbles soundly in fluids. No unwanted force is applied to the fluids. With this special character, Noritake is working on to develop new technology that is useful to both our lifestyle and the industries.
