Why is high purity quartz sand in short supply in the market?

High purity quartz sand and a very high-quality industrial material, and its performance is also very superior. Many projects will use high-purity yingsha as filler, such as glass, refractory, smelting ferrosilicon, metallurgical flux, ceramics, grinding materials, casting and other industry projects. Quartz powder has high whiteness, no impurity and low iron content. With its high quality performance, it has won the trust of customers and has a wide range of applications. So what are the specific functions of high purity quartz sand as engineering filler? Next, Jiangsu fused silica powder technical personnel to give you a brief introduction, for your reference.

1. As a filling product, it should meet the requirements of high electrical insulation and good resistance to immersion welding, and the high purity quartz sand is just the best one for engineering construction application.

2. The chemical, thermal and mechanical properties of quartz powder have obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1650 ℃. This is the characteristic that must be possessed as filling material, and it is also what users are happy to see.

3. High purity quartz sand is non-toxic and has no pungent smell. Using it as filling can ensure the environmental protection characteristics of the product and avoid environmental pollution, because it belongs to the endless environmental protection product.
