CONSTITUTION:The content of the ferromagnetic particles can be enhanced by reacting and hardening the phenols with aldehydes particles in an aqueous medium in the presence of a basic catalyst, and the average particle diameter of the produced composite particles can be adjusted to 1 - 10mum by controlling the concentration of the ferromagnetic particles at the time of reaction, thus permitting the obtained composite particles to have an average particle diameter of 1 - 10mum and a bulk density of &lt;=1.5g/cm and a content of the fine ferromagnetic particles of 80 - 99wt.%.</description><edition>6</edition><language>eng</language><subject>CINEMATOGRAPHY ; ELECTROGRAPHY ; ELECTROPHOTOGRAPHY ; HOLOGRAPHY ; MAGNETOGRAPHY ; PHOTOGRAPHY ; PHYSICS</subject><creationdate>1998</creationdate><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&amp;date=19980618&amp;DB=EPODOC&amp;CC=JP&amp;NR=2767063B2$$EHTML$$P50$$Gepo$$Hfree_for_read</linktohtml><link.rule.ids>230,308,776,881,25543,76294</link.rule.ids><linktorsrc>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&amp;date=19980618&amp;DB=EPODOC&amp;CC=JP&amp;NR=2767063B2$$EView_record_in_European_Patent_Office$$FView_record_in_$$GEuropean_Patent_Office$$Hfree_for_read</linktorsrc></links><search><creatorcontrib>HORAI SHIGERU</creatorcontrib><creatorcontrib>FUJIOKA KAZUO</creatorcontrib><creatorcontrib>TODA TETSUO</creatorcontrib><creatorcontrib>HAKATA TOSHUKI</creatorcontrib><title>JP2767063B</title><description>PURPOSE:To obtain composite particles having an average particle diameter of 1 - 10mum and a bulk density of &lt;=1.5g/cm and an enhanced content of fine ferromagnetic particles by advancing hardening reaction of a phenol resin simultaneously with its reaction in a first stage in specified conditions at the time of producing the fine composite particles comprising the fine ferromagnetic particles and the hardened phenol resin.
