Product Name: Ammonium Octamolybdate
English Name: Ammonium octamolybdate
Chinese Name: Ammonium octamolybdate

CAS No.: 12411-64-2
Molecular Formula: (NH4)4Mo8O26
Molecular Weight: 1255.66

Properties:
- White powder

Preparation Method:
Take 134.3 g of ammonium dimolybdate, 160.9 g of high-purity molybdenum oxide, and 675 mL of soft water. First, add the ammonium dimolybdate and soft water into a crystallization tank and heat while stirring (heating temperature: 80°C; stirring speed: 80 rpm). Once dissolved, gradually add the high-purity molybdenum oxide to adjust the solution pH to approximately 4.0. Slowly add 36 mL of 25 g/L lanthanum nitrate solution to the mixture, then add the remaining high-purity molybdenum oxide and adjust the pH to 2.0. Heat and stir at 80°C for 10 minutes, add make-up water, and continue the reaction for 2 hours. Finally, discharge, vacuum filter, and dry the product (drying temperature: 100°C; duration: 6 hours) to obtain ammonium octamolybdate with a 0.3% lanthanum doping level.
