Preparation of samples,high aluminium ceramic proppants

Discuss the firing temperature, particle size of raw material, additive and the addition of BaCO3 ceramic proppant acid resistance, crush resistance effect.

  The results show that, the development of samples in laboratory, the acid solubility as low as 0.75%, 86MPa < 2.5% broken rate. The addition of BaCO3 could significantly increase the acid resistance of ceramic proppant, as long as good control of the adding amount, significantly improve the crushing rate and can not cause.
