     Baoji Freelong New Material Technology Development Co., Ltd. loated in Baoji City--China's Titanium Valley,we are mainly doing Zirconium,Titanium,Nickel,Niobium,Tantalum etc metal material and other alloy's produce,OEM and Sales.and also exporting the goods what we make. we have a lot of trustful clients and partner.and also we were authority by some firms.At present,we were build our relationship with Australia,Korea,German,US,UK,Malaysia,AZ,Middle East,Taiwan,Etc. Our company always take the quality and service as our responsibility,We always get close even match the quality what our customer wanted and as for quality,we never say no and no reason for quality failure.

I. Product Overview
Material Characteristics: Manufactured from high-purity nickel (Ni). Nickel exhibits excellent chemical stability in reducing atmospheres and at room temperature, showing particular resistance to corrosion by alkaline substances.
Physical Properties: High melting point (approximately $1455^\circ C$); possesses good thermal conductivity, ductility, and oxidation resistance.
Appearance: Typically bowl-shaped or cylindrical, equipped with a tight-fitting lid; available in sizes ranging from $30\text{ ml}$ to $100\text{ ml}$ or larger.

II. Applications
Due to their unique resistance to alkalis and high temperatures, nickel crucibles are widely used in the following areas:
*Alkaline fusion and sample decomposition (primary application)
Note: Do not use with acidic fluxes (e.g., sulfuric acid, hydrochloric acid, nitric acid), as acids severely corrode nickel.
*Chemical analysis and laboratory testing
*Material preparation and heat treatment
*Industrial production

Capacity: 5-50ml (Custom designs available)

Types: Short-walled zircon crucibles, zircon crucibles with flanged edges, straight-walled zircon crucibles, sloping-walled zircon crucibles, cylindrical zircon                  crucibles

Surface: Glossy

Wall Thickness: 1mm, 2mm or customizable

Lifespan: 2mm thick crucibles have a longer lifespan than thin-walled crucibles and can be reused more than 100 times

Common Specifications

III. Usage Precautions & Temperature Control:
       The operating temperature for nickel crucibles generally should not exceed $700^\circ C$ (usually kept below $800^\circ C$); otherwise, oxidation occurs readily in air at high temperatures.
Prohibited Substances:
*Strictly avoid using strong acids (especially nitric acid or aqua regia) for cleaning or containment.
*Do not use for melting sulfides; at high temperatures, sulfur reacts with nickel to form low-melting-point nickel sulfide, damaging the crucible.
*Not suitable for prolonged heating of strongly oxidizing melts (other than carbonates).
Heating Method: Typically heated using an electric furnace or gas burner; avoid prolonged direct contact with flames that produce heavy carbon deposits to prevent the metal from becoming brittle.
