SEM high purity vitreous carbon planchet
Lapped surface on one side for smoothness, also known as glassy carbon or glass-like carbon. For analytical SEM/EDX, X-ray analysis and chemical analysis applications.
Vitreous carbon is an advanced materials of pure carbon combining glassy and ceramic properties with those of graphite. Impermeable to gases and liquids, high purity, corrosion resistant, thermal stability in air up to 600°C and in vacuum or inert gas up to 3000°C. Good electrical conductivity, low thermal expansion and extreme resistance to thermal shock. Hard and strong (hardness = 230 HV1). Applications in the fields of chemical analysis, metallurgy, crystal growth, medical technology and in glass and ceramics research.
High purity vitreous carbon with impurities less than 30ppm total.
