摘要: Abstract An approach using polydimethylsiloxane (PDMS) as mid-temperature strengthening phase in gelcasting for the fabrication of ceramic parts with complex internal cores was firstly proposed and adopted. The bending strength samples PDMS at 500 °C greatly improved from almost 0 to 1.037 MPa when 4 wt.% added. distinct networks formed by were responsible improvement which confirmed result scanning electron microscopy (SEM). Based on analysis X-ray scan, validity also testified experiments.
