Abstract Mechanical properties of porcelain based on feldspar as a matrix with SiC particles reinforcing phase were studied in terms the effects content, firing temperature, and holding time. A maximum flexural strength 122 ± 4 MPa was achieved for sample 8 wt% content treated at 1260°C 30 min, which is 90.6% high than that unmodified (64 5 MPa). The fracture toughness elastic modulus former 1.71 · m 1/2 89.975 GPa, respectively. Because thermal expansion coefficient (4.40 × 10 −6 /°C) smaller glass (6.60 /°C), remain state compressive stress after cooling. This characteristic restricts crack growth offsets tensile phase, restraining crystal owing to pinning grains, such mechanical are improved.
