Study on production technology of spherical graphite

Spherical graphite is also processed from flake graphite, and the processing technology of spherical graphite is relatively high. 1. Recombination of fine particles. Fine particle compounding is the use of fine particle compounding equipment to spheroidize powder

Preparation of Ultra‐High‐Purity Submicron Refractory

A method was developed for preparing ultra‐ high‐purity submicron powders of refractory oxides from transition metal alkoxides. Compounds of the type M(OR)3 and M(OR)4, where R is an alkyl group such as C4H9‐, were thermally decomposed to oxides at 325 to 450C at atmospheric pressure. Techniques were perfected to prepare, on a continuous basis, 99.95+% zirconia and hafnia with an

Focus Graphite's Proprietary Process Purifies Fine Flake

High purity graphite crucible operating instructions

the high-purity graphite crucible is one kind of graphite crucibles we produce. see Special Note bellow: 1. Be careful not to give mechanical impact, do not fall from a height or impact. 2. Do not be wet, should be stored in the dry place. 3. Building melting dull, do not make it touch the water. 4. Use the time not to direct the flame at the crucible (spray to the bottom of the crucible), if
