  • METHOD FOR PRODUCING A MATERIAL FOR CHEMICAL VAPOR DEPOSITION
    Publication number: 20100126351
    Abstract: A material for chemical vapor deposition of the present invention contains a precursor composed of a metal compound, and has 100 or less particles having a size of 0.5 ?m or more in 1 ml, in particle measurement by a light scattering type submerged particle detector in a liquid phase. A thin film can be prevented from being contaminated by particles even when a highly degradable metal compound is used as the precursor.
    Type: Application
    Filed: January 19, 2010
    Publication date: May 27, 2010
    Applicant: ADEKA CORPORATION
    Inventors: Masaru HOSOKAWA, Masakatsu MATSUSHITA, Satoshi NAKAGAWA

  • Titanium dioxide reduced in volatile water content, process for producing the same, and masterbatch containing the same
    Patent number: 6126915
    Abstract: Titanium dioxide powder with a greatly decreased volatile moisture content can be obtained by surface treating with titanium dioxide powder with addition of a calcium salt and/or a silane coupling agent, or by a surface treatment by addition of an aluminate together with these surface treatments. A masterbatch containing this titanium dioxide powder is of high quality, having no defect due to foam generation upon high temperature processing.
