Glass and Ceramic Industry


Glass Industry

The area where boron minerals are consumed the most is the glass sector. When boron is incorporated into the molten glass intermediate, it increases its fluidity and increases the surface hardness and durability of the final product. Boron oxide is intensively used, in particular, in borosilicate glass, textile and insulation type glass fibers.

Boron is used in borosilicate glass, textile and iso-type glass fibers, liquid crystal indicators, special ovenware, laboratory equipment, car headlight and signal glasses, glass wool, LCD (Liquid Crystal Display) screens and CRT glass products and certain special boron glasses are used in the aerospace industry, electronics industry and nuclear reactors and create boron research opportunities.

Ceramic Industry

Boron is mostly used in glaze and frit in ceramic industry. The proportion of boron oxide used in ceramic glazes varies between 8-24% by weight. The main function of boron oxide in glazes is to provide thermal compatibility between the glass and the material and to regulate the thermal expansion coefficient of the glaze. Another reason for the addition of boron to the glazes is the formation of glass in the early stages of melting. Borates also improve the appearance of the glazing by increasing the refractory index. The addition of boron to the glaze increases mechanical strength and scratch. Boron also increases resistance to the effects of chemicals and water. Boron, on the other hand, forms the basis for the addition of colorants.

Boron oxide can be used up to 20%, reducing the viscosity and saturation temperature of the enamels. In particular, 17-32% of the Crude materials added to the enamel are boron oxide, with watery borax being preferred. Boron, which makes ceramic scratch resistant, is added to the glazes in the form of colemanite in 3-24% ratio.
