Parameters of Competitive beta silicon carbide whiskers SiC whiskes
The parameter “beta” in competitive beta silicon carbide (SiC) whiskers refers to the number of defects per unit length, also known as “passivation defect density.” Beta is an important factor in determining the reliability and performance of SiC whiskers, as it affects their ability to withstand high temperatures and stresses.
The passivation defect density can be measured using various techniques, such as X-ray diffraction (XRD), scanning electron microscopy (SEM), or transmission electron microscopy (TEM). The β value is typically expressed in units of micrometers squared per millimeter, which represents the average number of defects per unit length along a particular axis (e.g., [100] for a 100-μm diameter beam).
In general, higher beta values indicate that SiC whiskers have fewer defects and therefore have better mechanical properties, but they may also be more susceptible to cracking under certain conditions. Therefore, selecting beta values that balance strength and durability is critical for practical applications in industries such as aerospace, automotive, and electronics.
