PHILIPPINES – Ateneo de Manila University researchers are exploring the mechanical properties of silicon carbide (SiC), a semiconductive ceramic found in space, to develop stronger versions of this material.
SiC, a compound of silicon and carbon, is crucial for various applications, from computer chips to heat shielding in spacecraft. While naturally occurring SiC is rare on Earth, it is abundant in meteorites and stardust, particularly around carbon-rich stars.
The research team, consisting of Clint Eldrick Petilla, Catherine Joy Dela Cruz, and Christian Lorenz Mahinay, examined how varying carbon content affects SiC’s mechanical properties, including its elastic modulus, tensile strength, yield strength, and toughness.
Their findings, published in the Japanese Journal of Applied Physics, indicate that increasing carbon content enhances SiC’s strength, peaking at a 25% carbon ratio. Beyond this point, however, the material weakens.
The researchers advise further studies using actual SiC samples to investigate additional factors, including the effects of temperature on its mechanical properties.
