The quality and stability of continuous basalt fiber production begin with the raw material. Basalt is a natural material with significant variations in mineralogical composition, structure and melting behavior. For this reason, the suitability of a particular basalt for fiber production cannot be determined only by its chemical composition or by visual inspection of the rock. Raw Material as the Foundation of Fiber Technology The selection and evaluation of basalt raw materials is an impo...

The development of continuous basalt fiber technology requires more than the optimization of individual pieces of equipment. Stable and efficient production depends on the interaction between raw materials, melting, melt preparation, fiber formation and process control. Technology Development One of the technology development projects involved the testing of a new generation of equipment and process solutions for continuous basalt fiber production. The objective was to improve the overa...

Introduction Basalt fiber (BF), known as “the green industrial material of the XXI-century”, combines ecological safety, natural longevity and many other properties. It is not a new material, but its applications are surely innovative in many industrial and economic fields, from building and construction to energy efficiency, from automotive to aeronautic, thanks to its good mechanical and chemical performances. Hence basalt fiber has gained increasing attention as a reinforcing material ...
