Quartz vs Alumina vs Sapphire Tubes | Furnace T...

Quartz tubes are ideal for low to medium temperature CVD and optical monitoring up to ~1100°C. Alumina tubes support high-temperature research up to ~1700°C and are chemically robust for oxide...

Sapphire vs Alumina vs YAG vs Quartz | Material...

For research applications requiring high temperature, strength, and optical clarity, sapphire is the superior material, outperforming alumina, YAG, and quartz. Alumina is the best low-cost ceramic for high-temperature environments, YAG...
