High-Alumina Dental Sintering Crucible – Ø90X35mm Round Open

Optimized for Dental Sintering: These crucibles are specifically selected for the precision requirements of dental zirconia sintering and prosthetic firing. They provide consistent heat distribution to prevent warping and discoloration of dental crowns and bridges during high-temperature cycles.

Important Usage Notice (Dental Lab Protocol): To ensure optimal results and avoid thermal shock damage, please observe these standard laboratory guidelines:

• Slow Pre-heating: Always ensure the crucible is pre-dried at 300°C before commencing the high-temperature sintering cycle.

• Controlled Ramping: Maintain a gradual temperature ramp-up and cool-down to prevent cracking.

• Safe Handling: Wait until the furnace temperature is below 300°C before opening the furnace door to avoid sudden thermal expansion stress.

• Note on Durability: As these are precision ceramic consumables, damage caused by thermal shock or mechanical impact is not considered a manufacturing defect.
