Feature: 1. WIDELY USED: Graphite crucible is commonly used in the melting of gold, silver and other metals, widely used in metallurgy, foundry, machinery, chemical and other industrial sectors for melting alloy tools and non ferrous metals. 2. STABLE PERFORMANCE: Graphite crucible can be heated and cooled quickly for melting precious metals such as gold and silver, and has good thermal shock resistance, electrical conductivity and thermal conductivity. 3. HEAT RESISTANCE: This graphite crucible has good thermal conductivity and high temperature resistance, small coefficient of thermal expansion during high temperature use, and certain strain ability for rapid cooling and heating. 4. CHEMICAL STABILITY: Good chemical stability, high temperature resistance, good oxidation resistance and corrosion resistance, long service life. Strong corrosion resistance to acid and alkali solutions. 5. HIGH PURITY GRAPHITE: Made of crystalline graphite, retaining various physical and chemical properties of the original natural graphite. High purity, high strength and high density. Specification: Item Type: Graphite crucible Product Material: Graphite material Outer Diameter Size: Approx. 25 x 24 x 12mm / 1 x 0.9 x 0.5in Inner Diameter Size: Approx. 20 x 18 x 7mm / 0.8 x 0.7 x 0.3in Product Description: 1.
