Tecnodieci zinc oxide is used in many different sectors. In the ceramic sector, it is used in glaze production between 5-15% according to the characteristics of the glaze. It is one of the sought-after raw materials because it improves the surface, expansion and cracking properties of the glaze. White pure zinc oxide, which is 99% Zno, called gold seal, is used in the glaze. It is produced in two ways; scrap zinc and oxidation method, zinc oxide produced from scrap zinc is not used much in the ceramic sector because it causes pollution and fixed quality problems.
Although there are some factories in our country that produce Zinc, there is a serious import. Since the price range is determined according to the London Metal Exchange, it varies between 3000-4000 USD / ton.
Zinc oxide Packaging is usually shipped in 25 kg Bags
Tecnodieci stocks always contain Zinc oxide.
Zinc Oxide; In addition to its melting effect at high temperatures, it is the most effective raw material used to reduce the viscosity of the glaze.
In Glaze Composition;
When used in small amounts: It provides the development of especially green and blue colors. It increases whiteness. Together with alumina, it regulates whiteness and opacities in glazes without boron and with low CaO content. It reduces the expansion coefficient.
When used in large amounts: During the cooling process of the glaze, zinc cyclicate (Zn2 SiO4) crystals are formed.
While zinc silicate crystals are formed, it collects pigments or color-giving oxides in the glaze and gives decorative features to the surface.
Zinc oxide; It is produced by volatilization of zinc metal or alloys containing high amounts of zinc and direct oxidation of zinc vapors. In commercial scale; There are zinc oxides of various purities according to their copper, iron, sulfate, lead and cadmium contents.
