Pliable glass strands form the structural backbone of fiberglass products, reinforcing the polymeric matrix and imparting many of the desired end-product characteristics. These are largely determined by the composition of the glass fibers which are engineered from quarry products and minerals, like regular glass. Subsequently, the conventional challenges of glass working and molten glass handling are just as prevalent in fiberglass production; particularly the challenge of refractory corrosion.

Platinum products have been used to protect refractory elements in furnaces from the corrosive behavior of molten glass in both general glass manufacturing and fiberglass production for years. Molten glass attacks refractories via two basic processes: a chemical interaction at the interfac...

Recent discussion within the industry has highlighted the importance of monitoring the intensity drift of X-ray tubes operating within XRF spectrometers used in the analysis of wide ranging materials.  (more…)

In XRF techniques the observed fluorescent X-ray counts are not directly proportional to concentration but must be corrected for absorption-enhancement effects caused by the influence of all other elements in the samples. (more…)
