Porous Ceramics materials are currently mainly used in the following areas.
As the Porous Ceramics with light, non-flammable, sound insulation, processing performance and decorative performance and other characteristics, in the construction industry has been widely used. With the closed pores can be used as the external walls, floors and ceiling veneer, cold storage of the insulation layer, can also be used as floating water; with openings can be used as concert hall, radio room veneer sound-absorbing material.
2 catalyst carrier
Because the Porous Ceramics material has high surface activity and adsorption performance, the catalyst is supported on the Porous Ceramics material, which can effectively increase the contact area of the chemical reaction, improve the reaction rate and conversion rate, so as to improve the catalytic effect. According to statistics, the current 90% of the world's vehicle catalyst carrier is a Porous Ceramics carrier.
3 filter separator
As the Porous Ceramics material has a high porosity, when the filtrate through, which suspended solids, colloids and microorganisms and other pollutants are blocked in the filter medium surface or internal, and finally to achieve the purpose of separation and purification. Mainly include: molten metal filter, remove the liquid metal debris and gas; precision filtration, such as sugar, brewing and tap water purification; gas separation and filtration, remove radioactive contaminants; fluidized partitions and electrolytic cell partitions The
4 biomedical materials
Porous bioceramics have good biocompatibility, good bone induction, stable physical and chemical properties, non-toxic side effects of the characteristics used to produce biomedical materials. Porous hydroxyapatite is used in the manufacture of artificial dental materials, artificial bone and so on.
5 aerospace wave material
The Porous Ceramics with closed structure has low dielectric loss, low density and low absorptivity of radar wave in unit thickness than other ceramic materials, which makes it have good application potential in aerospace materials requiring high permeability.
With the continuous improvement of the pore structure of the control materials and the continuous emergence of various new materials and high performance Porous Ceramicss, the application and application of Porous Ceramicss are also expanding.
In the future, the development direction of Porous Ceramicss will be mainly focused on the basic research on the pore structure control of porous materials, including the gradient pore structure, double pore structure, nanopore structure control and so on.
