Product Description

Dolomite

Introduction:

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg(CO3)2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.

Applications:

Dolomite is used in the body and glaze, and MgO and CaCO3 are introduced to replace talc and calcite. The function of MgO is to change the composition of the mixing system, so as to reduce the firing temperature of the body; Promote the dissolution of quartz and the formation of mullite, increase the amount of quartz, reduce the amount of feldspar, so as to increase the transparency of the body. Compared with calcite, adding dolomite to glaze is not easy to smoke, and crystallization rarely occurs, which is caused by double salt minerals. Dolomite mixture of dolomite and marl can be used to make anorthite and diopside - wollastonite clinker, suitable for fast firing porcelain. The clinker is cheaper than the calcium - magnesium compound synthesized alone in the manufacture of wall tiles and fine ceramics.
