We will be happy to recommend you soda feldspar similar to the sample you sent.

China, the word means not only China, but also porcelain. From this, we can see the influence of porcelain in the world. Our country is a big country of porcelain, and porcelain has been famous far and wide in ancient times. Among them, glaze is a very important material on porcelain. Glaze makes porcelain colorful and is loved by people all over the world. The glaze is actually made of feldspar, and a small stone can turn decay into magic. Sodium feldspar is the most common type of feldspar. Today, let's take a look at the technological properties and uses of sodium feldspar.

Process Characteristics

?

Between 1100 and 1300°C, it has good chemical stability and has a fluxing effect when co-fused with quartz and aluminosilicate. It is often used as a flux in the manufacture of glass and ceramic blank glazes and can reduce the firing temperature. Enamel raw materials Industrial feldspar and other mineral raw materials can be used to make enamel. In addition, sodium feldspar can also be used in the abrasive industry.

?

Main Application

Ceramic industry consumption accounts for about 30%, the consumption in the ceramic industry accounts for 30%, and the rest is used in other industries such as chemical industry, abrasives, glass fiber and welding rods.

?

Glass flux: Sodium feldspar is one of the main components of glass mix. Feldspar contains high Al2O3, low iron content, and is more fusible than alumina. It not only has a lower melting temperature, but also has a wider melting range. It is mainly used to increase the alumina content in glass ingredients, reduce the melting temperature in glass production and reduce the amount of alkali.

?

Ceramic Body Ingredients: Sodium feldspar can act as a raw material before firing, reduce drying shrinkage and deformation of the green body, improve drying performance and shorten drying time. During firing, it can be used as a flux to lower the firing temperature, promote the melting of quartz and kaolin, and interdiffuse and infiltrate in the liquid phase to accelerate the formation of mullite.

?

Ceramic Glaze: Ceramic glaze is mainly composed of sodium feldspar, quartz and clay raw materials, and the content of sodium feldspar can reach 10-35%. In the ceramic industry (blanks and glazes), potassium feldspar is mainly used.

?

Abrasives: Feldspar is often used as a component of ceramic cement in the manufacture of grinding wheels, and its content is 28-45%.
