Ferric phosphate (chemical formula FePO₄·2H₂O) has unique applications and performance characteristics in the field of ceramic manufacturing. Below is a detailed analysis of its specific applications and features in this domain:
I. Applications
1. Ceramic Metallic Glazes:
Ferric phosphate is an important raw material for producing ceramic metallic glazes, especially in metallic glazes for antique-style tiles. By adjusting formulations and processes, it can be used to produce a variety of metallic glaze tones such as platinum, red gold, gold, rust-like, copper-like, silver-like, purple gold, blue gold, black gold, and sand gold.
·It is suitable for different glaze production techniques, including raw material glazes, fired glazes, and dry granules.
·It can be applied in various glazing methods, such as screen printing, spray glazing, grinding glazing, covering glazing, and inkjet glazing.
2. Ceramic Inkjet Printing Metallic Inks:
Ferric phosphate is also a key raw material for ceramic inkjet printing metallic inks. It is compatible with production techniques involving fully fired and semi-fired materials (ferric phosphate + frit) and can produce metallic inks with strong metallic luster, stable coloration, and high adjustability.
3. Black Glaze for Daily Ceramics:
Ferric phosphate is used as a main raw material for black glaze in daily-use ceramics, providing a glossy black finish with a unique aesthetic appeal.
II. Performance Characteristics
1. High Purity and Activity:
Ferric phosphate features high purity and strong activity, ensuring the stability and consistency of ceramic glazes.
2. Environmentally Friendly and Non-Toxic:
Ceramic glazes made from ferric phosphate are environmentally friendly and non-toxic (lead-free and boron-free), meeting modern environmental standards for ceramic production.
3. Strong Metallic Luster:
Ceramic metallic glazes produced with ferric phosphate exhibit strong metallic luster, enhancing the texture and aesthetic appeal of ceramic products.
4. Stable Coloration:
Ferric phosphate ensures stable coloration in ceramic glazes, maintaining consistent colors during the firing process.
5. High Adaptability:
Ferric phosphate demonstrates strong adaptability to different metallic glaze production techniques, glazing methods, and firing conditions, meeting diverse customer requirements.
6. Improved Ceramic Properties:
Adding an appropriate amount of ferric phosphate to ceramics can significantly enhance their hardness, corrosion resistance, and thermal stability. This is because ferric phosphate reacts chemically with other components in ceramic materials at high temperatures, forming a more robust crystal structure that improves the overall performance of the ceramics.
Ferric phosphate offers extensive applications and unique performance advantages in ceramic manufacturing. By appropriately adjusting formulations and process conditions, it is possible to produce ceramic products with various tones and features to meet market demands.
