In metallurgy, a flux is a chemical reducing agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time. They are used in both extractive metallurgy and metal joining.

A fluxing agent (or softening agent) is required to lower the sintering temperature and save energy in the powder sintering method. Fluxing agents can act as softening agents at low temperatures and as pore stabilizers at high temperatures without affecting the …

Fluxes are substances, usually oxides, used in glasses, glazes and ceramic bodies to lower the high melting point of the main glass forming constituents, usually silica and alumina.

Apr 22, 2020 · In soldering, fluxing agents, or more popularly, a flux is a chemical that helps us make good solder contacts. The function of the fluxing agents (or flux) is somewhat like that of the primer in a painting job.

Mar 1, 2024 · Flux materials enhance the energy efficiency of ceramic and glass material production. Borates and fluorides offer promising alternatives to traditional fluxes. Boron oxide acts as a glass-forming agent with reduced viscosity at lower temperature. Sodium oxide effectively depolymerizes silicon-oxygen network.

Apr 20, 2018 · The paper describes the difference in the sintering process of dry pressed porcelain bodies based on the different fluxing agents (potassium feldspar rock, sodium potassium feldspar rock, sodium-calcium feldspar rock and bone ash) compared with quartz sand without fluxing effect.

According to Klemm and Skalny (1976), “a flux is a substance which decreases the melting point of the liquid phase, whereas a mineralizer is a substance that accelerates the rate of process or reac-tion occurring in the solid state within the liquid phase, or at the liquid-solid interface.”

As fluxing agent start melting (or softens) before ceramic body does, therefore it collapses the porosity and bonds the unmelted ceramic particles to each other by making a eutectic system. in...

SCF-1 Cupola Flux is a specially formulated cleansing agent recommended for use in cupola melting operations. It is designed to be added during cupola start-up and cupola melt-out where increased fluidity is needed in the slag to remove the ash generated from the coke.

uxing agents is to minimize the aluminium amount in the dross phase. The purpose of this project was to investigate if the uxing agent that is used by the cast house is having any impact on the quality of the billets. Therefore, for that purpose, samples with a variating amount of uxing agent were processed by the cast house in order to be ...
