Zirconium Silicate for Sale China
Zirconium silicate (zircon) is a mineral that has been known and widely used by people since prehistoric times. This is explained not only by its relatively wide distribution as an accessory mineral (which is part of other rocks) but also by its existence in a crystalline form. The largest crystals were found in Madagascar and weighed several kilograms. And this form makes it possible to use it in jewelry. Accordingly, the demand for this mineral was high hundreds of years ago.
Properties of the Zirconium Silicate
The chemical formula of pure zirconium silicate is ZrSiO4. More than 65% of the compound is oxide ZrO2. But in addition to zirconium silicate, the rocks may contain a lot of impurities. Most common:
- niobium, etc.
Depending on what impurities are present, a large number of varieties of the mineral are distinguished:
- hafnium zircon;
- uranium zircon and others.
The color that zirconium silicate has in nature depends on the presence of impurities. Zircon is often found in brown shades, white, colorless. Less common are golden red (hyacinth), greenish, and blue hues.
The transparency of the mineral ranges from almost complete to zero. The crystals have a diamond luster. Although this external feature, the similarity with diamonds ends.
Zircon is characterized by thermoluminescence (glow when heated) and cathodoluminescence (glow in a stream of electrons). Also, most of the known zircons fluoresce in light rays from the ultraviolet part of the spectrum.
There are large deposits developed on an industrial scale in Australia, the USA, India, Russia, Southeast Asia, Ukraine, South Africa, Mozambique, and China.
Application of Zirconium Silicate in Industrial Production
Due to its physical and chemical resistance, zirconium silicate, in addition to the already mentioned jewelry, is used in many areas of human activity.
This is the production of zirconium and hafnium from it, as pure metals. And the application in metallurgy as alloying additives. Zirconium silicate is actively used in the manufacture of ceramics with good hygienic characteristics, sanitary faience, ceramic tiles, and refractories. Zirconium silicate is used as an enamel silencer. With it, they are betrayed by a white and opaque color.
Zirconium Silicate Usage
- Engobes and glazes
- Refractory ceramics
- Ceramic tableware
Zirconium Silicate for Ceramic
In recent years, zircon used for glazing has been replacing other materials that were previously used in the ceramic industry, especially in the production of tiles and sanitary ware. The dispersity and chemical-mineralogical composition of Kreutzonit make it the most effective for silencing glazes, and also reduces the mass consumption of the silencing agent.
Zircon Grinding Media
The use of grinding media and liners guarantees fine grinding with the minimal ball and liner breakage while minimizing energy costs. With the help of the developed grinding technology, crystalline solids such as bauxite, zircon, corundum, silicon carbide, and ceramic pastes in any state can be ground to a particle size of the order of a micron. Some of the most common products are grinding balls, cylinders, and balls.
