1pcs Lab 5ml to 1000ml Cylindrical Corundum Crucible 99% Alumina Ash Crucible High Temperature Resistance 1600 Degrees(600ml)

1). High purity: Al2O3 > 99%, good chemical resistance2). Good temperature resistance, use for a long time at 1600 , 1800 in the short term3). Good resistance to cold and heat, and do not easy to crack.4). High density of grouting.

• 1. It is recommended to put the crucible into the oven at about 100 for 120 minutes to remove moisture when it is first used.
• 2. Corundum crucible can, acetylene gun or alcohol blowtorch direct heating, avoid the crucible heating uneven rupture.
• 3 crucible and heating body (such as: carbon tube, silicon molybdenum rod, heating wire) distance should be more than 2 cm.
• 4. The bottom of the crucible should not contact directly with the bottom of the furnace as far as possible. It is recommended to use corundum pieces and other temperature resistant objects to form convective airflow on the overhead to prolong the service life of the crucible.
• <5/ min, recommended 5 crucible heating or cooling speed below 1200, recommended
