Product Details
Crucibles are smaller containers used for the melting of materials, e.g. minerals and glass.
1.Material: 99% alumina, corundum-mullite ceramic, zirconium oxide ceramics optional
2.Shape: we are able to supply a variety of shape of ceramic crucibles, including cylinder, rectangular, square, boat and so on.
3. Features: all ceramic crucibles are with excellent chemical resistance, thermal - shock performance.
4. Working temperature: It can be work under max. 1600℃ long term.
5. Application: They are commonly used in a variety of metal or non-metal melting material, or melting items analysis in the lab, also it's a regular application for smelting & sintering for phosphors, rare earth material, precious metals.
Usage
In general, most of the materials to be analyzed and fired are first put into the corundum crucible, and then put into the analysis or firing equipment for heating.
Notes
(1)Before the first use of the crucible, please put it into an oven around 105℃ and bake for 120 minutes to remove the moisture.
(2)Do not use gasoline gun, acetylene gun, alcohol torch direct heating, to avoid the crucible due to uneven heating and burst.
(3)The distance between the crucible and the heating body (such as carbon tube, silicon-molybdenum bar, heating wire, etc.) shall be greater than 2cm.
(4)The bottom of a large crucible should not be in direct contact with the bottom of the furnace as far as possible.
(5)As the crucible material is alumina, try to avoid firing and alumina chemical reaction of the laboratory material.
((6)The The rate of warming or cooling cannot be too fast.Below 1200℃ should <5℃/ min, above 1200°C <4℃/min.It is suggested to turn on the power and control the temperature. If the power is turned off at high temperature, the early cooling speed may cause cracking if it is too fast.

Main Feature
1) High hardness.
2) High heat resistance: alumina ceramic has excellentthermal stability,which means that it is widely used in areas where resistance to high temperatures is essential.
3) Good wear resistance: alumina ceramic is the material of choice for alumina wear parts.
4) High electrical resistivity: alumina is an electrically insulating material.
5) High corrosion resistance: it is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance. Packing and shipping
