hromite powder is widely used in foundry coatings (also called mold washes or refractory coatings) to improve the surface quality of metal castings. 1. Role of Chromite in Foundry Coatings Chromite powder (FeCr₂O₄) is applied as a refractory coating on sand molds and cores to: Prevent metal penetration (burn-on defects). Reduce sand fusion (sand sticking to the casting). Improve surface finish (smoother castings). Withstand high

Chromite sand is a versatile material with several industrial applications, primarily due to its high melting point, thermal stability, and resistance to thermal shock. Here are the key applications of chromite sand: 1. Foundry (Metal Casting) Mold and Core Making: Chromite sand is used in foundries to create molds and cores for casting ferrous and

Chromite sand is widely used in the foundry industry due to its unique properties, making it suitable for various casting applications, particularly in ferrous and non-ferrous metal casting.

 Characteristics of foundry grade chromite sand: —1. Good resistance to alkaline slag and does not react with iron oxide. In practical applications, chromium ore sand can prevent thermochemical sand from sticking to the surface of the casting. —2. Chromite ore sand is an inert casting sand with a large wetting angle to molten steel. This

Chromite powder  has the following advantages as a glass colorant, combining its physical and chemical properties and industrial application requirements: 1. Strong high-temperature stability Chromite powder shows excellent stability in the high-temperature environment of glass melting (usually 1200-1500℃), and is not easy to decompose or volatilize. This ensures color uniformity and avoids color difference or

PRODUCT:CHROMITE SAND Chromite sand is a naturally occurring spinel consisting primarily of the oxides of chrome and iron. It is a by-product of ferro-chrome production and is mainly used in foundry applications and in glass production.
