Zirconium Silicate Opacifier
Product Description
- Zirconium Silicate Opacifier is a functional zirconium silicate product specially developed for opacifying and whitening application scenarios. It focuses on the hiding and whitening needs in glazes, coatings, enamel and other fields, and achieves higher opacifying efficiency through special particle size optimization. After 24 years of technical iteration and market verification, based on a large number of customer application data, we have precisely adjusted the particle size distribution of Zirconium Silicate Opacifier to make its particle size range form the best match with visible light wavelength, maximize the light scattering effect, and the opacifying and whitening effect is significantly better than ordinary industrial-grade zirconium silicate. The product uses Australian ILUKA high-purity zircon sand as raw material, through fine grinding and multi-stage iron removal processes, with high whiteness and few impurities. It is a core functional raw material for the ceramic, coating and enamel industries to improve product appearance quality.
- The core advantage of Zirconium Silicate Opacifier lies in the balance between high-efficiency opacification and cost optimization. With a high refractive index of 1.97 and optimized graded particle size, the unit opacifying efficiency of this product is more than 20% higher than that of ordinary zirconium silicate. Customers can reduce the addition amount by 15%-20% under the premise of achieving the same hiding power and whiteness, directly reducing the cost of formula raw materials. At the same time, the product has been optimized for dispersibility, is not easy to agglomerate in glaze slurry, water-based coatings and other systems, has good mixing uniformity, and the surface is fine and smooth after firing or film formation, without defects such as particle protrusions and pinholes. Zirconium Silicate Opacifier has stable chemical properties, is resistant to acid, alkali and high temperature, and can stably exert opacifying effect in different formula systems with strong adaptability. We have a variety of opacifying grades in stock regularly. Conventional orders can be arranged for delivery on the same day, and customized models can be delivered within 10-15 days, fully meeting the procurement needs of different customers.

After-sales Service
We provide full-cycle technical service support for customers who purchase Zirconium Silicate Opacifier. In the pre-sales stage, technical personnel will learn in detail about the customer's application system, target whiteness and cost requirements, recommend the most suitable product model and addition amount suggestions, and can also provide 500-1000g samples free of charge for customer testing and verification. In the sales stage, the order production progress is synchronized in real time, and the batch test report is attached with the goods. Export orders handle logistics, customs declaration and other procedures throughout the process to ensure on-time delivery of goods. In the after-sales stage, the exclusive contact person continues to follow up the product use effect. If customers encounter problems such as unsatisfactory opacifying effect and poor dispersibility during use, they will respond and communicate within 24 hours to assist in troubleshooting the causes of formula, process and other aspects, and provide optimization and adjustment solutions. We not only provide products, but also provide long-term application technical support to help customers achieve dual optimization of quality and cost.
Payment Terms
For the procurement scenarios of Zirconium Silicate Opacifier, we provide flexible payment schemes. For small-batch samples and trial orders, full payment before delivery is supported, with simple procedures and fast delivery speed to meet customers' needs for rapid testing. For large-batch formal orders, the settlement method of "50% prepayment upon order placement, balance settled before shipment" is adopted to protect the rights and interests of both parties to the transaction. We accept settlement in both RMB and US dollars, and support mainstream payment methods such as telegraphic transfer. For long-term and stable cooperative customers, stepped price discounts can be enjoyed according to annual purchase volume. The larger the annual purchase volume, the higher the unit price discount. High-quality core customers can also negotiate more flexible payment cycles. We adhere to the cooperation concept of mutual benefit and win-win results, and are committed to establishing long-term and stable partnership with every customer.
FAQ
Q: What is the essential difference between this zirconium silicate opacifier and ordinary zirconium silicate?
A: The core difference lies in the design logic of particle size distribution. Ordinary zirconium silicate is a general-purpose product, while Zirconium Silicate Opacifier is a functional product specially optimized for opacifying function. By precisely controlling the particle size range and distribution, it maximizes the light scattering efficiency, achieves better opacifying effect with less dosage, and has lower comprehensive use cost.
Q: Can it directly replace ordinary zirconium silicate in my existing formula?
A: It can be directly replaced, but due to higher opacifying efficiency, it is recommended to appropriately reduce the addition amount to avoid excessive opacity and reduce formula cost at the same time. Our technical team can provide specific replacement ratio suggestions based on the addition amount of your existing formula.
Q: What are the precautions for product storage? How long is the shelf life?
A: Please store in a dry and ventilated warehouse, sealed and moisture-proof. Zirconium silicate has stable chemical properties and will not deteriorate under normal storage conditions. There is no clear shelf life. As long as it is not damp and caked after long-term storage, it can be used normally.
