The use of zinc oxide grades plays a crucial role in the ceramics industry. This is because the material affects the glaze quality, color, and surface characteristics of the final product. Zinc oxide is useful as an additive in various ceramic formulations to help improve performance during the firing process. Each purity level has a different function. Therefore, its use must be in accordance with production needs and applicable quality standards.
The Role of Zinc Oxide Grades in Ceramic Production
In the ceramics industry, zinc grades are used to improve glaze quality and help produce smoother surfaces. This material also supports more stable color formation during the high-temperature firing process.
In addition to providing a better visual effect, zinc oxide helps increase the resistance of the glaze layer to fine cracks and temperature changes. Therefore, zinc oxide is widely used in the production of tiles, porcelain, decorative ceramics, and even sanitary ware.
Grades Used
In general, zinc oxide grades are distinguished by their purity level. While each manufacturer may have its own specifications, some commonly used grades are:
- Grade around 95–97%: for general industrial applications that do not require very high purity levels. This grade is still capable of supporting various ceramic production processes with standard requirements.
- Grades around 98–99%: Widely used in the ceramics industry because they provide more consistent glaze quality. This purity level helps produce more stable colors and smoother surfaces.
- Grades 99,5% or higher: For applications requiring premium quality. The very low impurity content creates a more uniform finish and is suitable for high-spec ceramic products.
These differences in purity levels affect material performance, both during the firing process and the quality of the final product.
Effect of Zinc Grades on Ceramic Glaze
The use of zinc grades significantly contributes to glaze formation. Zinc oxide helps increase surface gloss, making the product more visually appealing.
This material also supports the formation of a more stable glaze layer during the high-temperature firing process. As a result, the ceramic surface has better resistance to light scratches and discoloration.
Furthermore, the use of zinc oxide helps produce more even color distribution. As a result, product quality appears more consistent throughout each production run.
Utilization in Various Ceramic Products
Various products utilize zinc oxide grades as part of their raw material formulations. Floor tiles, wall tiles, porcelain, tableware, artistic ceramics, and even sanitary ware utilize zinc oxide. This enhances the visual quality and durability of the product.
In decorative ceramics, zinc oxide helps produce brighter colors and smoother glaze effects. Meanwhile, in technical ceramics, this material supports structural stability during high-temperature firing.
Today, advances in production technology allow zinc oxide to be processed with higher levels of purity, even achieving more uniform particle sizes. These zinc oxide grades support manufacturing process efficiency. Furthermore, this material can produce ceramic products with improved appearance, strength, and quality.
