Methods and techniques for preparation of micro-porous ceramics as filtration media in water treatment are presented and reviewed in this paper wherein micro -pore formation and moulding are pointed to be two key steps for the preparation.

According to the characteristicsofmicro-porousceramics,the filtration theory of micro-porous ceramics as filtration media in water treatment is discussed in this paper.

Thermal stress analysis for structural ceramics during laser beam machining;

Al2O3 structural ceramic has many advantages such as high strength, high hardness and good wear resistance.

Silicon resins have become an important joining material for structural ceramics.

Progress on research of joining structural ceramics with silicon resin;

As the present advantaged situation of rare-earth resources in our country,the application and mechanisms of rare-earth element in structural ceramics,such as Al2O3,Si3N4,ZrO2,functional ceramics,such as dielectric ceramics,piezoelectric ceramics,conducting ceramics and glaze materials were elaborated in detail through the rare-earth element atomic structure and chemical characteristic.

The influencing factors of high temperature creep of structure ceramics;

The results indicated: the PN-2,APN-2 high temperature active filler metals had good ability of plastic deformation,had good wetting property on structure ceramics,its could directly broze structure ceramics,structure ceramics and metals compone.

Structure ceramics are becoming popular materials for industrialcomponents, and grinding with diamond wheel has been widely used in theproduction of structure ceramics components.
