Basalt fiber from Indian Deccan Plateau. A preliminary study about the raw materials

Basalt fibers are one of the most interesting reinforcement which are being used in last few decades. The fibers are manufactured from basalt raw materials.

Necessary rock studies of the gabbro and andesite basalt groups for the suitability as the raw material base for the production of continuous basalt fiber (CBF). A unique technique including laboratory melting and pilot-industrial melting at the high-tech equipment.

The fiberizability of a basalt melt depends on several factors like mineralogy, surface tension, and emissivity coefficient. However, the most relevant parameter remains the viscosity.

In this paper the viscosity of several samples from Indian Deccan have been determined, by applying the model of Giordano et al. [5], based on their chemical compositions and they have been compared with commercial basalt fiber.

Even if the Deccan plateau is characterized by several different basalts with different chemical compositions, the results confirm that among them several Indian basalts would fit the requirements for a basalt fiber spinning plant.
