Siliconizing, during liquid silicon infiltration

From the above calculation, it is found that there is much less heat delivery per unit time during vapor silicon infiltration than liquid silicon infiltration. It is also noted that the driving force of molten silicon is greatly affected by the pore size (diameter), which might result in problem (clogging, etc.). However, gaseous silicon, acting like ideal gas, can enter into any open pore. 

The process consists of compacting a mixture of SiC and carbon, which is then infiltrated with liquid silicon. During the infiltration heat treatment, the following reaction takes place ...
