Ceramizable silicone rubber composites were prepared by using kilchoanite as ceramic filler, glass frit as flux, and nano silica as reinforcing agent. The effect of the content and size of kilchoanite on the tensile properties of the composites was studied. The ceramic specimens were obtained by sintering the composites at 1 000℃, and then the microstructure of its fracture surface was observed. The phase change of ceramic specimens was analyzed by X-ray diffraction, and its linear contraction and flexural strength were measured. The results show that the increase of the kilchoanite with the same particle size can reduce the tensile strength of the composites, while increase the elongation at break. Under the same content, the kilchoanite with a smaller size can improve the tensile strength of the composites. When the content of kilchoanite is too high or too low, the flexural strength and density of the ceramic specimens decrease. With the decrease of the size of kilchoanite, the flexural strength of the ceramic specimens increases, while the linear contraction also increases. The maximum flexural strength of the ceramic specimens can reach to 58.57 MPa by changing the content and size of kilchoanite.
