The results show that the SSFs' bending strength gradually increases and the openporosity falls with increasing the slurry loading in precursor;
研究发现：随前驱体中浆料浸入量的增加，泡沫制品的抗弯强度逐渐提高，开孔率有所降低；
2
Correlation coefficients between the thermal conductivity and bulk density, openporosity, permeability and raw material grade was obtained respectively.
另外，还计算了导热系数与体积密度、显气孔率、透气度和原料等级之间的相关系数。
3
So that, it is necessary to adopt very sinterable UO2 powder and suitable pelleting and sintering conditions to minimize openporosity and small porosity.
