Graphite Plates are divided into high purity graphite plates、graphite electrode plates、flexible graphite plates.graphite plates has features of high density、high strength、low porosity、ablation resistance、acid and alkali resistance etc,so they are important material for the metallurgical furnace、resistance furnace、refractory lining materials、chemical equipments、machinery
Molded graphite High density / Fine grain size / High purity / High strength / Low specific resistance / Ease of precise machining; Excellent thermal shock resistance to high temperature and oxidation / Good anticorrosion
Abstract: A granulated powder for a high-density sintered body is provided, which has an excellent flow rate and an excellent sintered density, and a sintered body produced using the same is provided. The granulated powder is obtained by granulation using a binder and a powder material comprising small diameter particles comprised of stainless steel and having an average particle diameter of 1 to 20 &mgr;m and large diameter particles comprised of stainless steel and having an average
A maximum sintered density of 2.85 gcm−3 (relative density is 98%) was obtained when the compaction velocity was 9.4 ms−1. The radial and axial shrinkage were controlled to less than 1% at a
Graphite as anode, generally do not need special treatment, but to choose high purity, high density, high strength (so-called "three high" graphite) graphite on the line, this graphite in brush plating operations are often used as anode material.

Aug 09, 1994 · Step 6: Open HIP furnace, retrieve HIP canister and remove graphite. Experimentally, the density of high purity hot pressed graphite (from Poco Graphite Inc.) was increased by 15% from 1.83 g/cc to 2.10 g/cc by HIP processing in accordance with the invention at 2200° C./206.8 MPa/2 hrs. Longer hold times should yield even higher density.
The production process of high purity graphite depends on whether the product is isotropic graphite or anisotropic graphite. The process can be divided into three types. The similarities and key technical problems between the production of three-high graphite and the production of graphite electrodes are briefly introduced as follows:
