Description
I UNITED S A EDWARD cooDmcHAoHEsoN,
CANADA, ASSIGNUR TOOWILLIAM FALLs, NEW YORK.
PATENT oFFIoE.
OF STAMFORD TOWNSHIP, ONTARIO,
AOHESON SMITH, OF NIAGARA To all whom it may concern.-
Be it known that I, EDWARD GooDmoH ACHESON, a citizen of the United States, residin in Stamford township, Ontario, Canada, have invented certain new and useful Improvements in Refractory Articles and Method of Making the Same, of which the following is a specification.
The present invention relates to the production of crucibles or other refractory coherent articles or bodies of a compound of silicon, carbon, and oxygen.
The invention comprises both the method of producing such articles and the product thereof.
In manufacturing fire-bricks by molding a moistened mass of finely-divided siloxicon, whichis a compound of silicon, carbon, and oxygen, and firing to develop the self-bonding property, as disclosed in my Patent No. 722,793, of March'17, 1903, I have noticed that when the bricks are heated in an oxidizing atmosphere the surface is harder and tougher than the interior. I therefore concluded that the action of oxygen increases the self-bonding property.
The present invention is based on this observation that the self-bonding property of silicon, carbon, and oxygenis increased by the action of oxygen.
In carrying out my present invention I mold or otherwise shape the compound of silicon, carbon, and oxygen into a body and fire it. under oxidizing conditions throughout the body. For this urpose the finelydivided compound'is pre erably mixed with a small amount of an oxidizing agent. It is desirable that the oxidizing agent thus added should not liberate its oxygen at a low temperature. A ents which have been found suitable for t e purpose are metallic oxids, such as those of manganese, iron, or chromium. The presence of free carbon inthe mixture or the addition of carbon thereto is not detrimental to the self-bonding property. In practice 1oyingninetytwo parts, byweight, of the compound of silicon, carbon, and oxygenforexample, s1lox1conone ,part of manganese dioxid, seven parts of carbon, and a sufficient amount of a liquid--such as water, petroleum, or glycerin ora viscous one, such as water and dextrlne,to brmg the mass Specification of Letters Patent. dpplicatiogi filed September 23,19Q5. S rial N 279,855.
the articles may beproduced by' Patented Nov. 20, 1906.
into a plastic state. The constituents are preferably finely divided and intimately mixed. The mixture is then shaped in any usual way and fired, preferably at a red heat. In order to subject the article to a high and uniform temperature, it is preferably embedded in carbon and fired in an electric furnace.
While it is to be understood that the precise nature of the 'efiect produced by the oxidizing agent and of the free carbon, if present, is not accurately known and that the scope of this invention is independent of theory, it has been found that the above ma terials furnish a mixture which is well adapted for the purposes intended. Crucibles have thus been produced which on account of their high heat conductivity, chemical inertness, and durability are especially suitable for the use of steel and brass founders.
While the described method is that preferably employed, articles of suflicient strength for many uses may be made by simply molding a mixture of the finely-divided compound of silicon, carbon, and oxygen with a tempo-' rary binder and firing the mixture under oxidizing conditions throughout the b0dyas, for instance, in an, atmosphere of compressed oxygen.
I claim- 1. The process of producing refractory coherent articles, which consists in shaping a mass of'a compound of silicon, carbon and oxygen and firing the shaped body under oxidizing conditions throughout the body.
2. The process of producing refractory coherent articles, which consists in mixing a finely-divided compound of silicon, carbon and oxygen with an oxidizing agent, molding the mixture. and firing the molded body.
3. The process of roducing refractory coherent articles, which consists in mixing a finely-divided compound of silicon, carbon and oxygen with ametallic oxid, molding the mixture and firing the molded body.
4. The process of roducing refractory coherent articles, whic consists in mixlng a finely-divided compound of silicon, carbon.
and oxygen with an oxidizing agent and carbon, molding the mixture and firing the molded body.
'5. As a new manufacture, an article consisting of a molded and fired body of particles of a compound of silicon, carbon and oxygen,.
the component particles having been sub- I jected to oxidizing conditions during the firing 7. As a new manufacture, an article con sisting of a shaped and fired mixture of a compound of sihcon, carbon and oxygen, an
- oxidlzing agent and carbon.
8.A s a new manufacture, an article consisting of a molded and fired mixture of a compound of silicon, carbon and oxygen and I 5 a metallic' oxid. g g
9. As a new manufacture, an article'consisting of a molded and fired mixture. of a compound of silicon, carbon and oxygen, a
metallic oxld and carbon.
