Refractory high alumina ceramic crucible for thermal analysis

high temperature resistant cylindroid rectangular alumina tray crucible is used for laboratory testing and a variety of industrial thermal analysis. There are alumina ceramic crucible and corundum crucible include arc alumina crucible, square alumina crucible, rectangle alumina ceramic crucible, column ceramic crucible and a variety of shaped alumina ceramic crucible.
Advantage:

  • 1) Low density

  • 2) High hardness

  • 3) High corrosion and wear resistance

  • 4) Moderate to extremely high mechanical strength

  • 5) Moderate thermal conductivity

  • 6) Very high compressive strength

  • 7) Excellent chemical resistance

  • 8) Acid resistant/alkali resistant

Size: 5ml, 10ml, 15ml, 20ml, 25ml, 30ml, 50ml, 100ml, 150ml,200ml – 2500ml
 
Characters of thermal analysis alumina crucible and corundum crucible:
 
1) High purity: Al2O3>99%, high chemical etching resistance;
