Thermal Resistant High Purity Graphite Crucible For Sale graphite crucible

Introduction

1. Graphite crucible can be used for non-ferrous metal smelting and casting, dissolving gold

or silver ornaments, analysis of special type steel, sintering hard metal.

2. graphite crucible for smelting gold is specialized in melting gold in headgear and jewelryindustry. That requests graphite material has high density and purity, ablation-resistance, and it can be used many times. We can machine various crucibles accordingto customer's requirement.

3. Machined from high pure graphite and widely used in the gold,silver,platinum and other noble metal's melting.If it's used in oxygen atmosphere,it wil start to be oxygenized when the temperature is higher than 700-800°c. If it's used in the protective atmosphere, it can stand more than 2000°c.

4. widely used in such fields as industrial furnaces, mono-crystalline silicon machinery, mono-crystalline silicon machinery, electron, semi-conductor, metallurgy, oil, chemistry, textile, electrical machinery, electrical equipment, electrical furnace, traffic, communication industry, medicine, etc.

Features:
Graphite /carbon crucibles with high dense, low resistivity, oxidation resistance, corrosion resistance, high temperature resistance, good electrical conductivity, etc

High quality material----PITCH Coke

We use the best graphite material to produce our carbon graphite products!
