What is the use of feldspar powder in industrial production?
2024/05/24
Feldspar, the general name given by geologists to the feldspar group of minerals, is a mineral containing calcium, sodium and potassium, and is one of the more common minerals in the earth's crust as well as the main mineral component of igneous rocks. The feldspar powder, is the powder of the mineral, ceramics, glass, enameling industry feldspar powder are generally rich in potassium or sodium, so in the glass manufacturing industry feldspar powder has been widely used, but thankfully feldspar powder price is not particularly expensive.
Generally speaking, feldspar powder use is in the industrial aspect, the main use of the industry, including glass manufacturing, ceramics, enameling, and abrasives, welding electrodes and other industries, which in the ceramic industry feldspar powder use amounted to 30%.
In the glass manufacturing industry, feldspar powder has a high Al2O3 content, low iron content, and compared to alumina is more fusible, can be melted at low temperatures in the melting colleague to broaden the melting range, and thus become the main component of the glass mixture, but also to improve the content of alumina in the glass ingredients to reduce the amount of alkali. At the same time, after the feldspar powder melting, in the progress of glass molding than other mixed raw materials are slower than the ability to reduce the crystallization, which can prevent the glass formation process because of the crystal and damage. Therefore, glass mixing is the main use of feldspar powder containing potassium and sodium in general.
