Chromium ore flour 325#400mesh for ceramic glaze
Chromium ore flour can be added in ceramic glaze, because its excellent physical and chemical properties. Chromite flour has good heat resistance, chemical corrosion resistance and high hiding power, which makes it play an important role in the field of ink.
First of all, the physical and chemical properties of chromium ore flour are the basis for its use in making ceramic glaze. The main component of chromium ore powder is chromite, with a chemical formula of Cr2O4, FeO, containing oxides of chromium, iron and magnesium. Its color is black, with a low hardness, Mohs harness is 5.5, a density between 4.4-4.8 g/cm³. These properties make chromite powder useful as a pigment, especially in applications that require high hiding power and chemical corrosion resistance.
Secondly, the specific application of chromite powder in ink pigments includes the following aspects:
Heat resistance and chemical corrosion resistance: it has good stability at high temperatures, is resistant to thermal shock, and is resistant to corrosion of glass and slag. These characteristics enable it to withstand various printing and use conditions in inks, maintaining color stability and durability.
High hiding power: when used as a pigment, chromite powder can provide high hiding power, making the color of the ink more vivid and durable.
Environmental protection: As a natural mineral material, chromite powder is more environmentally friendly than some chemical synthetic pigments and meets the environmental protection requirements of modern ink production.
In summary, chromite powder is widely used in the production of ink pigments due to its excellent heat resistance, chemical corrosion resistance and high hiding power, providing stable color and excellent printing effect for the ink.
Our chromite ore powder, also known as chromium powder, is made from high-quality L6 layer chrome ore imported from South Africa. It is a natural ore. After washing, drying, crushing, screening, grinding and other processes, different types of chrome ore sand and chrome ore powder are produced.
