Titanium monoxide properties: golden yellow powder. Do not dissolve in water, nitric acid, soluble in sulfuric acid, partially dissolved in dilute hydrochloric acid to form trivalent titanium ions and produce hydrogen. The chemical properties are not stable, and the titanium dioxide is heated in a carbon electric furnace or reduced by a reducing agent such as zinc, magnesium or hydrogen. Used in the manufacture of titanate semiconductors.

Tantalum pentoxide (Ta2O5) is a white colorless crystalline powder that is the most common oxide of lanthanum and the final product of lanthanum combustion in air. It is mainly used as a single crystal of lithium lanthanum silicate and a high refractive low-dispersion special optical glass. It can be used as a catalyst in chemical industry.
The zinc selenide material is a yellow transparent polycrystalline material having a crystal grain size of about 70 μm and a light transmission range of 0.5-15 μm. The synthesis by the chemical vapor deposition (CVD) method is substantially free of impurity absorption, and the scattering loss is extremely low. Due to the small absorption of 10.6 μm wavelength light, it is the material of choice for making optics in high power CO2 laser systems.
Zirconium oxide (ZrO2) is a natural zirconia mineral raw material mainly composed of oblique zircon and zircon. Zircon is a deep mineral of igneous rock. Its color is yellowish, brownish yellow, yellowish green, etc. It has a specific gravity of 4.6-4.7 and a hardness of 7.5. It has a strong metallic luster and can be used as a raw material for ceramic glaze. Pure ZrO2 is a high-grade refractory raw material with a melting temperature of about 2900 ° C.
Zinc sulfide is a white to gray or light yellow powder. See the light color darken. It is stable in dry air and gradually oxidizes to zinc sulfate when it is exposed to humid air or contains moisture. Soluble in dilute mineral acid, soluble in alkali, insoluble in water.
Magnesium hydrogen phosphate mainly has three hydrates of anhydrous, trihydrate and heptahydrate, colorless or white orthorhombic crystal or powder; slightly soluble in water, soluble in dilute acid, insoluble in ethanol, relative density 2.013; heated to 205 At ° C, one molecule of crystal water was removed. It is decomposed into pyrophosphate when heated to 550-650 °C. Magnesium hydrogen Hydroxide heptahydrate was heated to 110 ° C to form magnesium hydrogen phosphate trihydrate, and magnesium hydrogen phosphate trihydrate was heated to 205 ° C to remove 1 crystal water.
1. Light magnesium oxide method
The light magnesium oxide method is the reaction of magnesium oxide and hydrogen peroxide:
Magnesium peroxide, chemical formula MgO2, white powder, odorless, tasteless, deliquescent. Do not dissolve in water, but will slowly decompose in water, soluble in dilute acid. Mainly used in medicine and other industries. It can be prepared by reacting a soluble magnesium salt solution with hydrogen peroxide.
