Description of Gr1 Gr2 Titanium Crucible

A crucible is generally a vessel or melting tank made of extremely high-temperature resistant refractory metal material. It is mainly used to evaporate solutions, crystallize, or burn solid substances.

Gr1 Gr2 Titanium Crucible is often made of titanium material through powder metallurgy and casting processes. It has high specific strength, good dimensional stability, high plasticity, wear resistance, corrosion resistance, high damping, high tensile strength, high temperature resistance, non-toxic, purity, High performance, and long service life.

Gr1 Gr2 Titanium Crucible is the most commonly used high-temperature vessel for sapphire single crystal extraction. It is often used in coating technology, rare earth metal smelting, glass smelting, crystal production, medical equipment, the electronic industry and engineering, and other industries. It should be noted that the crucible is used to extract crystals at high temperatures and needs to be placed on an iron tripod for safe operation.

The Manufacturing Process of Gr1 Gr2 Titanium Crucible

• Raw materials: Grade 0 titanium sponge → three-stage vacuum arc melting → 1100 ℃ multi-directional forging → finishing rolling → 750 ℃ vacuum annealing, grain size ASTM 7-9, straightness ≤0.5 mm/m.
• Forming route:
