In the field of high-end glass manufacturing, whether it is the crystal-clear photovoltaic panels or the electronic cover plates that emphasize both strength and appearance, the birth of their outstanding performance all begins with the extreme demand for basic raw materials. Potassium nitrate, as an indispensable key component in glass formulas, its purity directly determines the light transmittance, internal strength and production yield of the finished glass. Today, we are bringing to the glass manufacturing industry a dedicated high-purity potassium nitrate with a purity of over 99.6%, aiming to be a reliable foundation for you to enhance product quality.
Purity is the foundation, and low impurities are the key to high performance
For glass manufacturing, the purity threshold of 99.6% is merely the starting point. What truly affects the process and the quality of the finished product is the impurity content of less than 0.4%. Trace amounts of water-insoluble substances, chloride ions and excessive moisture can all be the “culprits” behind the formation of bubbles, stones, white spots or a decline in thermal stability in glass.
Our dedicated potassium nitrate, through precise process control, has achieved deep purification of multiple key impurities
- Extremely low water-insoluble matter: Effectively reduces solid-phase impurities during the glass melting process, significantly lowers the risk of bubbles and internal defects, and brings you a more uniform and pure glass liquid.
- Strictly control chloride ions: Avoid potential corrosion to refractory materials and heating elements in kilns, while ensuring the optimal performance of glass chemical stability.
- The contents of iron (Fe), copper (Cu) and other heavy metal ions are stably controlled at extremely low levels
These seemingly minor indicators together form an important defense line to ensure the smooth operation of your production line and improve the rate of superior products.
