Potassium Feldspar AF-03

Insoluble potassium-bearing rocks represented by potash feldspar in China are extremely rich, with geological reserves of nearly 100 billion tons. Therefore, the comprehensive utilization of potash feldspar to produce potash fertilizer (potash salt), aluminum salt is of great significance.

Light transmittance and whiteness are better than those of ordinary potash feldspar.It is one of the few potassium feldspar that can be used to make domestic ceramics.
Potassium feldspar contributes to densification, homogenization and whitening of porcelain. In the process of ceramic firing, potassium feldspar can promote the formation of porcelain phase, and make the porcelain phase more dense, so that the porcelain body more uniform, dense and delicate.
In Ceramics, Feldspar acts as a flux to control the temperature provide hardness and durability. It has good fluxing properties. It may melt at high temperatures compared to Sodium Feldspar but after firing it results in a stronger ceramic body
At the same time, it is the main vitrifying agent in Ceramic bodies. The Majority of white ware Bodies contains good Proportions of potash Feldspar. It acts as a flux in the ceramic Industry the Flux is defined as that Portion of the body which develops glass Phase.
Also Smaller Quantities are used in the manufacturing of Tiles, white ware, and sanitary ware.
In the ceramic industry (blank and glaze) is mainly used potassium feldspar.
We could like to give you suitable suggestion about Fritted according to your detail application.
In order to ensure its optimum quality, it is thoroughly examined by our skilled professionals on various parameters before the final dispatch.
The standard packing units are 50 kg HDPE Bags, 1250 Kg jumbo bags. However, we can also make the packing units as per customer requirements.
With its high K2O, low Iron (Fe2O3) & Titania (TiO2) contents and due to stringent process controls, K-Par range of Potassium feldspar products assure the tableware markets of desired level of fusibility confirming to specified constraints, the required level of whiteness and excellent base for coloring.

Use of Potassium feldspar:
1、 Glass Flux: Feldspar is one of the main components of glass mixture. Feldspar has high Al2O3 content, low iron content, and is more fusible than ALUMINA, not only has low melting temperature and wide melting range, and is mainly used for improving the content of ALUMINA in glass ingredients, reducing the melting temperature in glass production and increasing the content of alkali. In addition, the process of melting feldspar into glass is relatively slow, and the crystallization energy is small, which can prevent crystals from being precipitated during the glass forming process and damage the product. Feldspars can also be used to adjust the viscosity of glass. Generally all kinds of glass mixtures use potassium feldspar or albite.
2、 Ceramic body ingredients: Before firing, the feldspar can act as a barren raw material, reduce drying shrinkage and deformation of the body, improve drying performance and shorten drying time. can be used as a flux to reduce the sintering temperature during firing, promote the melting of quartz and KAOLIN, and mutual diffusion and penetration in the liquid phase to accelerate the formation of mullite. The feldspar glass body formed in the melting process is filled among the mullite grains of the blank body, so that the blank body is compacted and voids are reduced, thereby improving the mechanical strength and dielectric properties of the blank body. In addition, the formation of feldspar glass can improve the light transmittance of the body. The doping amount of feldspar ceramic body varies with different raw materials and different requirements of products.
3、 Ceramic Glaze: The ceramic glaze is mainly composed of feldspar, quartz and clay, and the content of feldspar can reach 10% -35%. In the ceramic industry (blanks and glazes), potash feldspar is mainly used.
4、 Enamel raw material: The feldspar and other mineral raw materials are mainly mixed into the phalanx. Feldspars are typically incorporated in an amount of 20 -30%.

5、 Abrasive: Feldspar is commonly used as ceramic cement in the production of grinding wheel, and its content is 28% - 45%.
