8 Sizes Alumina Ceramic Al2O3 Crucible Cup/Boat Without Cover 1000°C Free Shipping Worldwide

Caution: Please dry these crucible for 30mins in dryer or muffle furnace at the temperature of 150°C and then put them in dry place before putting them into use.

How make signs on the surface of these crucibles:
1, Write with solution mixed with blue ink and ferric chloride on the surface;
2, make them dry at room temperature naturally;
3, Put them into the muffle furnace and make temperature upto 815 degrees, and then keep 5 minutes.

Advantage:
High density, high purity.
Good wear-resistant, sealing ability.
Good tensile strength.
Good high temperature tolerance.
Excellent cold crushing and thennal shock resistance.
Excellent chemical stability and corrosion resistance.
No staining for long-term use.
Excellent insulating ceramic material.

Application:
Wildly used in all kinds of laboratory analysis and various industrial analysis, metal and nonmetal material sample melting.
Widely sued for high temperature application, like metal processing, glass melting, rapid thermal cycling, gemstone purification for jewehy industry.Widely applied in the metallurgy, chemical industry and materials science, etc.
Please Note: These are precision technical ceramic components. There is no warp
or camber on these items. They are straight and round. The thermal shock resistance is
not very high so exercise rule of thiunb caution. “
The larger the piece of material the slower
the rate of temperature increase should be applied to the piece.’ Heat up slowly to avoid cracking in use.
Alumina crucibles are made of aluminum oxide 99.5% purity. These products
are highly resistant to chemical attack and are especially useful for jobs that require
high tempe be sued in reducing, oxidizing and vacuum atmospheres. They are inert under hydrogen
atmosphere and are highly resistant to alkaline media and have excellent resistance to abrasion and wear.
ratures pollution-free results.

Matters needing attention:
Ahunina products are fragile. They must be handled with care and
avoid collisions during handling. Check the product to check for any cracks, in which case they should
not be used.Ahunina products must be dry before use. If drying is done in ovens,
make sure the process is carried out slowly. Avoid contact of hot product with cold surfaces alumina.
Ahunina products should not be heated in ovens or furnaces without flame control heating rate
and heating rate cannot be 50t /10mins. Besides it cannot be used over 1700¡ãC. The uneven heating may
cause its cracking.
