Refractory materials maintain physical and chemical stability at high temperatures. Dead-burned magnesium oxide, which is produced in shaft and rotary kilns at temperatures over 1500oC, has reduced chemical reactivity and therefore is suited to refractory applications.
Modern products have created a demand for glass that is ultrathin, but yet of higher strength than traditional glass affords. Glass can be strengthened thermally or chemically. The chemical strengthening of glass arose in the 1960’s. Chemical strengthening involves the process of potassium-for-sodium ion exchange, creating a layer of higher molecular compression on the glass’s […]
