Specification:
Package include:1pc
Used temperature: long-term Use temperature: ≤1600℃, sintering temperature: 1800℃,
Alumina content: 99.32%.
Precautions for use:
Cooling with the furnace temperature; Remember to be hot and cold
; Remember to heat with open flame; Cannot smelt metal.
Crucible in the first use before please put 105℃ or so in the oven to bake for 120 minutes to remove moisture.
Can not use gasoline spray gun, ethylene gun or blowtorch direct heating, to avoid uneven heat products and crack phenomenon.
The temperature change below 1200 ° C should be less than 5 ° C/min, and the temperature change above 1200 ° C should be less than 4 ° C/min. It is recommended to use electricity to control temperature during cooling.
The distance between the product and the heating body (such as carbon tube, silicon molybdenum rod or heating wire, etc.) should be > 2cm.
Large crucible bottom as far as possible not direct contact with the bottom of the furnace, it is recommended to use corundum foot pads and other temperature resistant substances will be elevated crucible, the formation of air convection, in order to extend the service life of the product.
Purpose classification: all kinds of laboratory metal, non-metal sample analysis and molten materials, used for laboratory and various industrial analysis.
