UNITED STATES PATENT OFFICE.
HE RY NOEL POTTER, OF NEW ROCHELLE, NEW YORK, AsSIGNOR TO GEO. WESTINGHOUSE,
. OF PITTSBURG, PENNSYLVANIA.
TREA'EMENT OF SILICON MQNOXID.
' Be it known that I, HENRY NOEL r or'rnn, a citizen of the United States, and resident of New Rochelle, county ofWestchester, State of New York, have invented certain new and useful Improvements in the Treatment of Silicon Monomid, of which the following is a specification.
. In a certain application for Letters Patent of the United Statesfiled December 30, 1904, Serial-Number 238,925, l. describe a new product, the same being silicon monoxid, and
aprocess for making the same. The process set forth inthe aforesaid application may be described as consisting in heating a mixture of silicon dioxidand carbon to a critical temperature in a partially filled inclosing' chamber. The product may appear in at least tWo forms, one a vitreous form, and the other a finely divided impalpable powder having a soft brown color. The color while in itself attractive, and perfectly adapting the powder for certain uses, might be less serv ceable for other uses and for this reason I have devised amethod of alteringthe brown color. This can be done m several ways, but for the purpose of producing a white powder I find that this can be done by blowing the brown powder through a flame or inany 7 other way oxidizing the powder while suspended in air and therefore unable to frit to- Specification ofLetters Patent.
Patented Dec. 29, 1908.
Serial No. 265,171. (Speoimena) gether. By this process the brown monoxid powder is changed into the dioxid of a fineness which appears to be equal to that ofthe original monoxid powder. The change in color removes any objection which may exist to the use of the powder as a tooth powder, for example, or as an ingredient of many other light colored powders, such as face powder. Both thebrown monoxid powder and the white dioxid powder are easily available for these purposes by reason of their extreme fineness, their non-poisonous nature,
and their good spreading qualities. It will be. understood, however, that the lighter color of the dioxid powder may be preferred for the purposes indicated, and also for many other urpos'es which will readily suggest themse ves.
I claim asmy invention:
The method of producing from finely subdivided silicon monoxid, silicon dioxid of equal fineness, which consists in burning the powder of silicon monoxid while suspended in an oxidizing atmosphere.
York, and State of New York, this 9th day of June A. D. 1905. 1
