99.95% Potassium Metaphosphate (KPO₃) CAS 7790-53-6 for High-Purity Phosphate Materials, Optical Glass, and Functional Material Applications

1. Product Overview

Potassium Metaphosphate (KPO₃) is an important high-purity phosphate material.

99.95% high-purity potassium metaphosphate features higher purity, lower impurity levels, and a stable polyphosphate structure, making it suitable for applications with stringent requirements for material performance and impurity control.

Compared with ordinary industrial grade potassium phosphates, high-purity potassium metaphosphate places greater emphasis on:

-Product purity;

-Metal impurity control;

-Batch-to-batch stability;

-Material application consistency.

For the Russian market, this product is mainly targeted at high-purity material enterprises, specialty glass companies, functional ceramic enterprises, research institutions, and fine chemical traders.

7. Frequently Asked Questions (FAQ)

Q: Which industries primarily use 99.95% potassium metaphosphate?

A: It is mainly used in high-performance phosphate glasses, functional materials, specialty ceramics, high-purity phosphate systems, and research applications.

Q: What is the difference between 99.95% potassium metaphosphate and ordinary potassium metaphosphate?

A: The 99.95% high-purity grade has stricter purity and impurity control, mainly for specialty materials and high-performance applications; ordinary grade products are mainly used for conventional industrial purposes.

Q: Why is high purity required for potassium metaphosphate?

A: High purity minimizes the impact of impurities such as Fe, Na, Ca, and Mg on material performance, improving product suitability for optical glass, functional materials, and other applications.

Q: What is the difference between potassium metaphosphate and potassium dihydrogen phosphate?

A: Potassium dihydrogen phosphate is an orthophosphate, mainly used in agriculture, buffering agents, and conventional industrial applications; potassium metaphosphate has a polyphosphate structure, more suitable for glass, ceramics, and specialty material systems.

Q: What documents are required for purchasing potassium metaphosphate in Russia?
