Note

1 The amount of Al 2 O 3 equals to the balance after 100% minus the loss on ignition and the actual amount of impurities listed above.

2 The chemical composition listed is  calculated according to 1h of dried  basis with  the  temperature  ranging 110 o C ± 5 .

3 The  impurity  composition listed  is  stipulated  according to Provision  5.2  of  GB8170  round  number  requirements.Appearance: Aluminum Hydroxide  is  white powder or  sand-like crystal, with  no  impurities.

Water contained: The amount of  water  contained should  be  less than  14%

Extra requirements on Quality: If there is  any  special  requirement  on  quality  from  the  customer, it should  be  negotiated  and  settled  down  by  both  sides.

Testing method: the testing  method  of  chemical  composition  and  water  contained  in  Aluminum  Hydroxide  should  be  carried  out  as  defined  in GB6610.

Chemical properties: the  density  of  Aluminum  Hydroxide  should be  2340-2390kg/m 3 , as  an  amphoteric  water-containing  oxide, Aluminum Hydroxide  can  be  considered  either  as  an  alkali  or  as  an  acid. It can have chemical reaction  with  either  alkalis  or  acids.

Main  uses: it is mainly  used  to  produce  aluminum  oxides ,other  Aluminum  Hydroxide products, various  inorganic  aluminum  salts  such  as  fluoride  aluminum,  cryolite  and  vitriolic  aluminum,  fire  retardant  and  water  purifier.

Packing: It is  packed  in  plastic-coated  woven  bags  or  woven  bags  with  plastic  film, with net  weight  of  each   bag  equaling  to  50  kg.  If  there  is  any  special  requirement  from  the  customer, negotiation  and  confirmation  is  needed.  The  packing  of  exported  products  needs  to  be  checked  or  accord  with  the  requirements  from  the  overseas  customers .  on  the  outside  package,  there  mark  the  content ,name  of  product,  registered  brand ,serial  number,  net  weight,  supplier  and  the   manufacturing  place.

Quality  certificates: attached  to  every  product,  there  is  a  quality  certificate ,  on  which  there  are  supplier,  name  and  brand  of  product, serial  number  and  weight  ,testing  result  and  the  marks  by  the  quality  supervising  institutions  ,quality  standard  number, and  the  manufacture  date.
