High temperature resistance High temperature resistance Chemical resistant Note: · Please put the crucible into an oven at 105℃ for 120 minutes to remove moisture before using it for the first time. ·Do not use gasoline spray guns, acetylene guns, and alcohol blowtorches to heat directly to prevent the stacking pot from bursting due to uneven heating. ·The distance between the stacking pot and the heating element (such as carbon tube, silicon molybdenum rod, heating wire, etc.) should be greater than 2cm. ·The bottom of the large crucible should not be in direct contact with the bottom of the furnace. It is recommended to use corundum pieces and other temperature-resistant materials to raise the crucible to form air convection and prolong the life of the stack. ·The heating or cooling speed cannot be too fast. Below 1200°C it should be <5°C/min, and above 1200°C it should be <4°C/min. It is recommended to turn on the power to control the temperature for cooling. If the power is turned off directly at high temperature, the early cooling rate may cause cracking. If there is any VAT tax that happens during import in the buyer's country, it should be paid by the buyer. Thanks for your understanding.
