Refractories

Refractory products

Features	１．They are used as jigs or containers for various heat treatment processes. ２．Products with various shapes such as a column plate, supporting column, and setter can be produced. ３．The product has a smooth surface since it is produced by pressure casting. ４．Complex shapes can be produced, but a general thickness is approximately 15 mm from the viewpoint of the nature of the forming method. ５．The base material can be selected from among three types depending on the intended use.

Ceramic foam

New material developed by Bridgestone having a high porosity which breaks stereotypes

Structural feature Feature of material	It has a high porosity (80 to 90%) and three-dimensional skeletal structure with a series of air holes. Thus, a high filtering performance can be obtained while maintaining a low pressure loss. It has a small apparent specific gravity (0.35 to 0.60) and is lightweight. As it has a large surface area, it can obtain a high efficiency of contact reaction.
quality Feature of	It excels in heat resistance. It excels in chemical resistance. Various shapes
manufacturing method	The cylinder solids, cylinder hollows, and other various shapes can be produced.
Type	1. Material quality Standard material…Blend of cordierite and alumina Please contact if you wish to use other materials. Note: Activated alumina coating is also available.

CerAntre

Ceramic madreporite with high-porosity spherical cell structure

Countless numbers of spherical cells from submicron to millimeter sizes are pierced continuously.

Madreporites are needed for various fields including purification of wastewater and tap water, precision filtration of industrial water and air, sterilization in the medical and cosmetic fields, precision filtration of solutions, food, and drinks, and separation of gas.
Materials using metallic or organic polymer macromolecules are well-known as this kind of madreporite. However, such materials are imperfect because they have a lower corrosion resistance and heat resistance.
Recently, Narita Seitosho Co., Ltd. has developed a ceramic madreporite with a high-porosity spherical cell structure composed of countless numbers of continuous spherical cells that exhibits the excellent thermal and chemical stability of ceramics. This ceramic madreporite with a high-porosity cell structure has uniform foam-like air holes which break the stereotyped view of conventional madreporite materials.
