calcium carbonate

"aragonite: an orthorhombic mineral form of crystalline calcium carbonate, dimorphous with calcite."

文石结晶富钙碳化物的一种正交晶矿物,具有方解石的两种晶态。

The value of oil absorption, viscosity of Nujol mull, specific surface area, contact angle, distribution of particle size and dispersivity of the calcium carbonate particles were also characterized.

对改性前后碳酸钙粉体的接触角、吸油、石蜡糊粘度、粒度分布、分散性等性能进行了比较。

Calcifuge Describing plants that grow on soils containing very little calcium carbonate, such as sandy or peaty soils and cannot grow on basic substrates such as most chalk and limestone soils.

在碳酸钙含量低的土壤中存的植物，例如在沙地或泥地中。这种植物在石灰石之类的碱性基质中不能。
