Embodiment 1
[0025] Manganese fluorosilicate production process: including the following steps:
[0026] 1) Preparation of materials: take fluosilicic acid and manganese hydroxide in proportion, add them to the reaction kettle,
[0027] 2) Mixing: heat and pressurize the reactor;
[0028] 3) Filtration: filter the reacted product to obtain filter residue and filtrate;
[0029] 4) Filter residue treatment: filter the filter residue with a filter press, the solid becomes solid waste, and the filtrate is used for standby;
[0030] 5) Filtrate treatment: Evaporate, dehydrate and dry the filtrate obtained in step 3) and step 4) to obtain manganese fluorosilicate product.
[0031] The invention puts the fluosilicic acid and the manganese hydroxide into the reaction kettle to carry out the heating and pressurizing reaction, the reaction time is short, and the product purity is high.
Embodiment 2
[0033] Manganese fluorosilicate production process: including the following steps:
[0034] 1) Preparation of materials: Take fluosilicic acid and manganese hydroxide in proportion and add them to the reaction kettle. The amount of fluosilicic acid exceeds 5% of the proportion.
[0035] 2) Mixing: heat and pressurize the reactor;
[0036] 3) Filtration: filter the reacted product to obtain filter residue and filtrate;
[0037] 4) Filter residue treatment: filter the filter residue with a filter press, the solid becomes solid waste, and the filtrate is used for standby;
[0038] 5) Filtrate treatment: Evaporate, dehydrate and dry the filtrate obtained in step 3) and step 4) to obtain manganese fluorosilicate product.
[0039] Add more fluosilicic acid to make the manganese hydroxide react completely.
Embodiment 3
[0041] Manganese fluorosilicate production process: including the following steps:
[0042] 1) Preparation of materials: take fluosilicic acid and manganese hydroxide in proportion, add them to the reaction kettle,
[0043] 2) Mixing: heat and pressurize the reactor, the temperature of the reactor is 110°C, and the pressure is 0.15 MPa;
[0044] 3) Filtration: filter the reacted product to obtain filter residue and filtrate;
[0045] 4) Filter residue treatment: filter the filter residue with a filter press, the solid becomes solid waste, and the filtrate is used for standby;
[0046] 5) Filtrate treatment: Evaporate, dehydrate and dry the filtrate obtained in step 3) and step 4) to obtain manganese fluorosilicate product.
[0047] Limiting the temperature and pressure in the reactor can make the reaction of the materials in the reactor more complete.
