Ventra - Cutting edge carbon graphite products and solutions
Machined Precision Parts
Graphite crucibles for melting, holding and transferring non-ferrous metals, precious alloys and semiconductor materials. High density and low porosity limit metal penetration and slag attack.
Features
High density (>1.75 g cm⁻³) – low metal penetration, longer campaign life
Good thermal shock resistance – safe transfer from furnace to pour station
High purity grades available – total ash <200 ppm for electronic-grade silicon
Wide shape flexibility – straight, spouted, tapered or lip-pour designs
Industrial Applications
Metallurgy
Melting and assay crucibles for gold, silver, platinum
General Industrials
Holding crucibles for die-casting cells
Semiconductor
Czochralski crucibles for single-crystal silicon pulling
