“…This is due to the effect of Fe 2 O 3 , as a change in the redox conditions causes a change in the coloring and an increase in the light interruption of the glass. 17) However, this does not pose a problem because the difference between the transmittance and haze values of ARGF_CN samples was 1%.…”

In this study, we fabricated E-glass bers and alkali-resistant (AR)-glass bers with a 7 mass% zirconia content, and AR-glass bers with a 7 mass% zirconia and 30-50 mass% refused coal ore content. The obtained bers were characterized for their tensile strength and alkali-resistant properties after dipping the bers in an alkaline solution. The alkali test results, based on microscopic images, showed that the AR-glass bers with 7 mass% zirconia and 40 mass% refused coal ore had better chemical resistance than the E-glass bers. The average tensile strengths of the E-glass bers and the AR-glass bers with 7 mass% zirconia and 40 mass% refused coal ore, after being dipped in an alkaline solution for 48 h, were 240 and 343 MPa, respectively. In addition, after an alkali test for 72 h, the average tensile strength of AR-glass bers with 7 mass% zirconia was 277 MPa, and the average tensile strength of AR-glass bers with 7 mass% zirconia and 40 mass% refused coal ore was 296 MPa. The AR-glass bers with a high tensile strength and low berizing temperature, fabricated using refused coal ore, can be widely used as alkali-resistant glass bers.

Foamed glass was fabricated by using glass powder and foaming agents. For the glass powder, we used sodalime glass which's manufactured by using refused coal ore obtained as by-product from Dogye coal mine in Samcheok. And for the foaming agents, we used Calcium carbonate, Calcium phosphate and powder of shale type refused coal ore itself which has high content of carbon materials. We additionally used liquid binder for forming, and mixed together. And we formed rectangular shape and treated 800 o C for 20 min in an electrical furnace. The various kinds of foam glass samples were fabricated according to the kinds of foaming agents. The physical properties of samples, as specific gravity and compressive strength, were measured. Pore structure of each samples were investigated too. Foam glass with specific gravity of 0.4~0.7 and compressive strength of 30~72 kg/cm 2 . Especially we get satisfying foam glass sample with low specific gravity of 0.47 and high compressive strength of 72 kg/cm 2 by the use of liquid calcium phosphate as foaming agent. It also had small and even shape of pore structure. Therefore, it is concluded that refused coal ore can be used for raw materials to manufacture secondary glass products such as a foamed glass panel for construction and industrial materials.

E-glass fiber is the most widely used glass fiber for reinforced composite materials of aircrafts, automobiles and leisure equipments. But recently researches are being progressed to reduce boric oxide from 8 % to 0 (zero), as is called 'Boron free E-glass', because of increasing material cost, environmental problem, and improving chemical resistance and mechanical properties of E-glass fiber. In this study, we fabricated the bulk glass and fiber glass of 'Boron free E-glass (BF) compositions', and characterized thermal properties and optical properties. 'Boron free E-glass (BF)' was obtained by the melting of mixed batch materials at 1550 o C for 2 hrs with different Al 2 O 3 compositions 5~10 %. We obtained transparent clear glass with high visible light transmittance value of 81~86 %, and low thermal expansion coefficient of 4.2~4.9 × 10 −6 / o C and softening point of 907~928 o C. For the chemical resistance test of 'BF' fiber samples, we identified that the higher alumina contents gives the better corrosion resistance of glass fiber.
