Zirconia

Detailed Product Description

Zirconia (ZrO2) nature of zirconium oxide mineral raw materials, mainly has inclined zircon and zirconium stones. Zirconium stones is igneous rock deep mineral, color has weak yellow, palm, yellow green wait, specific gravity of 4.6, 4.7, 7.5, hardness with strong metal luster, but for ceramic glaze materials used.
White heavy amorphous powder or single square crystallization. Without odor. Tasteless. In 1100 ℃ above four party formed crystals, in 1900 ℃ above form cubic crystals. General often contain a small amount Ha dioxide, and sodium carbonate formation eutectic zirconium acid sodium, zirconium acid sodium water in sodium hydroxide and hydrolysis into almost insoluble in water of the hydrogen zirconium oxide. Soluble in 2 copies of sulfuric acid and a mixture of water, soluble in acid and nitric acid, hydrofluoric acid, slow soluble in almost insoluble in water. The relative density of 5.85. Melting point 2680 ℃. Boiling point 4300 ℃. Refractive index of 2.2. Half to death (amount of mice, celiac) and mg/kg. Stimulating.
Pure zirconium oxide is a kind of advanced refractory raw material, and its melting temperature is about 2900 ℃ it can raise the high temperature and to expand the viscosity glazes viscosity changes of temperature range, good thermal stability, its content is 2%-3% when, can improve the performance of cracked glaze. Also because of its inertia big, the chemical can improve the glaze chemical stability and acid and alkali resistant ability, still can have opacifying agent role. In building ceramic glaze materials for use, more than the amount of zirconium stones commonly 8%, 12%. " The glaze under white" main raw material, zirconium oxide yellow pigment for good help color agent, if you want to get a better vanadium zirconium yellow pigment to must choose the pure quality zirconium oxide.
