Features:1. It has electric and heat conductivity, stress corrosion, expansion coefficient is small .Since good lubricity and processing properties. 2. Good resistance to corrosion resistance; Can be applied to all kinds of reactions crucible, tube, etc. 3. The high thermal conductivity and thermal stability performance; Gold, of molten silver etc all kinds of high temperature resistant products 4. Enough mechanical strength and impact resistance; 5. Easy to machining, can according to the geometry of the processed into a of products. Specifications: Materials : graphite Graphite content: 99.9 Melting point: 3850 50 : 4250 Size: 50mmX50mmX20mm Application: Graphite blocksrods used in silicon carbide furnace, graphitization furnace and other metallurgical furnace, Resistance furnace lining and material, and the permeability of graphite heat exchangers. Widely used in electronics, metallurgy, industry, steel and other fields, Products are of good quality, stable performance. Use note: 1. Be careful not to give a mechanical impact force, not from a fall or impact. 2. Dont wet by water, should be stored in dry place. 3. The crucible after drying, dont contact with water. color:black Package Contents: 1 x High graphite Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is - 1-3cm.
