Research of the evaporation law of elemental antimony
The variation of the weight of elemental antimony with time is measured by a vacuum differential weight furnace, and the evaporation rate of elemental antimony is obtained by mathematical statistical analysis at temperatures of 973–1473 K and ambient pressures of 5–500 Pa. The experimental results show that: when the temperature is supplied during melting, antimony should predom-inantly occur as SbIII. Noble metals, such as silver, gold, or platinum occur in glasses and melt as metals or in an oxidized 1,300 to 1,400 C in an induction furnace using a Pt-crucible. Afterward, the glass melt was stirred for 1.5 to 2.0 h using a rotation frequency of up to 100 min-1Noble metals Pt, Au, and Ag as nucleating agents in

Analysis of Antimony Sulfide Oxidation Mechanism in
Antimony is considered an important metal, and various antimony compounds are widely used in electronics, flame retardants, chemicals, alloys, and semiconductor materials. 1 Antimony exists mainly in the form of antimony sulfide, which is usually smelted by volatilization in the blast furnace. However, the process has some As antimony is typically present in industrial and commercial products only in small amounts, the concentration of antimony in waste types is low and a limited amount of antimony is currently recycled. One product relatively rich in antimony is the metal oxide varistor (MOV) used for overvoltage protection in electric circuits. To increase the Recovery of Antimony: A Laboratory Study on the Thermal

Selecting the Right Unit for Efficient Induction Melting
The stirring action in a properly sized induction furnace produces a homogeneous melt without gas pickup, refractory inclusions or alloy loss. Melting times can and should be exceedingly fast. Typical recommended melting times for iron are as follows: 300-500 lbs. in about 22 minutes; 750 lbs. in about 27 minutes; 1,000 lbs. in about 36 minutes.The polytherms of the surface tension of these melts have a linear character, the removal of antimony from the Fe–Sb–Al2O3 melts depends on the time of melting in a vacuum induction furnace(PDF) Modeling of Material and Heat Balance of
