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.
