Silicic acid is an oxide of silicon, which is widely distributed and accounts for about 60% of the earth’s crust, making it the largest element of earth and rocks. It exists and is distributed in nature in a variety of different forms.
Ceramics is an industrial production field in which silicate resources are processed at high heat, hence the name silicate industry. Silicic acid is mainly used as a refractory material, but in the ceramic industry it is also used to prevent shrinkage of the substrate, to add a white color to the substrate, to increase the refractoriness of the substrate, to make the substrate siliceous to adhere well to the glaze without flaking, and to prevent cracks in the glaze.
