白云石的微化反应与有序度

THE MICROCHEMICAL REACTION AND THE DEGREE OF ORDER OF DOLOMITE

试验证实白云石的微化反应特征明显受有序反的影响：白云石粉未在稀盐酸中的起泡程度随有序度的降低而加剧，在苗素红溶液中的染色程度和速度随有序度的降低而增强。低有序度白云石或完全无序的原白云石，其微化反应与方解石极为相似，反之，高有序度白云石与菱镁矿相似。另外还讨论了白云石微化反应的机理。

Experiments have confirmed that the characteristics of the microchemical reaction ofdolomite are obviously affected by the degree of order.The bubbling degrees will become acutewith the reduction of the degree of order when the dolomite powder is put in the dilute hydrochlo-ric acid.The de8ree and the velocity of coloratin will become fierce with the lowering of the de-gree of order when the dolomite power is put in the solution of alizarin red.The dolomite of lowdegree of order or the protodolomite of degree disorder,has the same characteritics of microchemi-cal reaction as calcite. Conversly,the dolomite of high degree of order has the same reaction asmagnestic,This paper discusses the mechanism of microchemical reaction of dolomite.
