Factors affecting porosity of ceramics.
Factors affecting strength of ceramics strength of ceramics is thus determined by many factors.
It is equivalent to the existence of a defect which can cause stress concentration accelerate crack growth reduce the bonding strength between grains and seriously affect the mechanical properties of ceramics under the action of friction force the pores may connect with each other to form a crack source accelerating the.
2 features of porous ceramic and standard characteristics.
Their hardness apart from other factors ceramic materials porosity has a sizable effect on it.
Maksarov et al 2014.
The porosity and impurities in the ceramic material can be fully eliminated and the grain size of the ceramic material can be properly controlled to make the product close to the theoretical density through the use of high purity ultra fine raw materials with as few additives as possible and strict process control when preparing ceramics thus transparent ceramics were prepared.
Lower the stress a material can support.
Ceramics porosity also decrease the cross sectional area over which a load in applied.
