Basalt Roving – Assembled basalt roving consists of several strands, drawn at the facility for the production of continuous basalt fiber and then assembled together, at assembling machines. The multifilament yarns of assembled roving are made of basalt scrap.

Basalt Reinforcing Mesh – Consists of bound filaments of basalt fiber, by adding polymer matrix. Basalt fiber has high durability and low thermal conductivity, and it is resistant to aggressive environments. Due to these qualities, basalt reinforcing mesh is more often applied in the construction instead of the metallic one. It does not require a special storage and it is resistant to precipitations and temperature changes. Basalt reinforcing mesh also reduces the thickness of the asphalt coating.

Basalt Fiber/Chopped Strands - short extracts of basalt fiber, applied in the reinforcement of binding mixtures. Chopped strands are produced from roving, which is chopped at special choppers. Basalt fiber is resistant to chemicals. In comparison with metallic fiber, basalt fiber is resistant to corrosion, it increases the ductility of concrete structures and eliminates micro cracks.

Basalt Yarn Basalt yarn is manufactured by melting chopped basalt rocks in а furnace under the temperature of 15000C. The large amount of iron oxide in basalt rocks gives the stone typical dark color and increases the homogenization and the temperature of crystallization. Concerning the viscosity, basalt yarn is steeper than fiberglass yarn.

Undoped yttrium aluminum garnet is an optical material similar to sapphire. Undoped YAG is widely used in UV and IR optics due to its mechanical and chemical characteristics.

Due to its dielectric and crystallographic properties, sapphire is an outstanding material for producing various wafers for electronic applications. Sapphire is the basic material in LED production, as its crystal lattice allows the growth of an epitaxial layer of gallium nitride (GaN) with fine performance characteristics and a favorable price/quality ratio; also, it is considerably widely used.

Single crystal alumina (Al2O3)

YAG has some excellent optical and other properties.

Nd:YAG crystal, which continues as the best of the rare earth garnet materials that are characterized by four-level laser operation which permits low threshold pulse and cw operation, is the most mature and widely used solid-state laser material adopted by R&D, medical, industrial and military customers.
