Glassy carbon offers high purity, corrosion resistance, thermal stability, and a structure impermeable to both gases and liquids

• Resistance to all wet decomposition agents
• No memory effects (uncontrolled adsorption and release of foreign elements)
• No contamination of analytical samples
• Stability to acid and alkaline melts
• No wetting effect of metal melts
• Good resistance to thermal shock allows rapid heating and cooling times
• Resistive to abrasive wear
• Good electrical conductivity

These crucibles are designed for high-temperature differential thermal/thermal gravimetric analyses and ultra-high purity materials technology involving crystal growing.

Alta Aesar's glassy carbon products are subjected to a high temperature heat treatment which imparts special material properties, including significantly improved corrosion resistance and strength.
