Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Ammonium metatungstate as an intermediate in the production of catalysts
Environmental release category (ERC):
ERC6a: Use of intermediate
Contributing activity / technique for workersopen allclose all
Name of activity / technique:
Step 1: Raw material delivery and storage - The substance is delivered and stored as a solution.
Process category (PROC):
PROC 2: Chemical production or refinery in closed continuous process with occasional controlled exposure or processes with equivalent containment conditions
Name of activity / technique:
Step 2: Transfer of liquid raw material into production equipment - The liquid substance is pumped into production equipment
Process category (PROC):
