The effect of MgSO_4 and some chelating agents on stability of H_O_2 was studied, it was shown that, in strong caustic, H_2O_2 has the best stability in the presence of MgSO_4 at lgC_(Mg)≈3, and the composite of sodium triphosphate with MgSO_4 was obviously superior to sole MgSO_4.
The effect of the grinding aid agent (sodium silicate,sodium citrate,sodium triphosphate)on the superfine-grinding process of sericite were studied in this paper .
Sodium triphosphate is present in the carbonized residue (heat treatment temperature of 900?C) in the form of NaPO3 (metaphosphate) and Na4P2O7 (pyrophosphate).
Primarily localized in not very ordered areas of HC, sodium triphosphate decreases the intensity of their thermal decomposition, and the processes related to intense degradation probably take place as in the more ordered (crystalline) areas.

The effect of the grinding aid agent (sodium silicate,sodium citrate,sodium triphosphate)on the superfine-grinding process of sericite were studied in this paper .The effect of sodium triphosphate is the best ,the effect of sodium silicate is the worst .When the amount of sodium triphosphate is 0.20%,the effect of the grinding aid agent is the best.
