Feldspar isn't just a pretty face in the world of minerals; it's incredibly useful too. This mineral plays a huge role in industries like electronics, where it's used in manufacturing, jewelry for its beauty, and even in construction materials. The 12 Different Types Of Feldspar And What They Look Like
The type of feldspar raw material, i.e., the division into K–Na–Ca feldspars is one of the most important pieces of information for the future use of raw materials. The content of the abovementioned cations determines the dominant technological properties, such as water absorption, firing temperature, shrinkage dependence on burning, and ...
The new method of preparation of glazess based on well defined grain size of groups of raw materials. Raw materials were divided into four groups: Quartz, Feldspars, Zircon silicate and all the others (wollastonite, talc, kaoline and zinc oxide). They were separately milled in order to obtain each specified grain size.
