PROCESS OF MAKING- SILICON NITRID.

No Drawing.
To all whom 171: may concern."
. e it known that l, Am SINDING-LARSEN, a .ibject the King of Norway, residing at (ll ristiania, Norway, have invented certain new and useful improvements in Processes of lilanufactru'ing Silicon Nitrid; and I do hereby declare the following to be a full, clear, and exact description of the invention,
suchas will enable others skilled in the art to which it appertains to make and use the same.
The present ii'ireution has ifLl its object a process or manufacturing silicon nitrid, accor-din to which this latter product is obtained in a finely 'rided state at the same time as a complete ll; reformation of the silicon into nitrid is secured.
As is well known pure s1" temperatures very casi ly con'ibiee gen, but it is very dillicult to obtain a quantitative transtoequation into nitrid, as only the surface of the silicon will be acted upon owing to the fact, that the nitrid already formed to a certain extent protects the subjacent part of the silicon against further action. it the silicon however is dissolved in a or the like, with which it forms an alley or compound, which is fluid at the temperature, at which the reaction takes place between silicon and nitrogen, for instance silico-iron, alui'niniuni silicid or another silicid, and this alloy or compound at a suitable temperature treated with a current of nitrogen, the entire amount of silicon will be transformed into nit d, which '3 produced in such a finely diy that it is capable of being directly ployed as a manure, or ifdesired it could be ployed for the manufacture of oxide oin' gen and through this latter into other 11' .7
gen compounds, while the silica oluained by ,the oxidation process can again be worked on ni'l'ridi By this process a silicid oi? a n'ictal could also be freed from its content of silicon, so that for instance from aluminium silicid such obtained by totally reducing aluminium silicates, in addition to the valuable nitrid of silicon could be obtained 1netallic aluminium.
This process, which may be carried out in an electric inductionor resistancefurmlce of such a construction as to allow of the supply and preheating of the current of nitrogen and also if desired of employing pressure, maybe conducted in such a manner that the other component of the silicid for Specification of Letters Patent.

instance aluminium is distilled over into a suitable vessel.
The following is an example of how the process may he carried out. in alloy of alun'iiniu n and silicon, containing equal parts of each component and which may have been. produced by totally reducing an aluminium silicate, is heated in a converter shaped furnace lined with silicon nitrid and kept at a temperature of about 2000 centigrade. 'lhrough the fused rloy or melt is then. drawn a currentof nitrogen, which. keeps the bath violently stirred at the same time the ilicou. content of the bath grail ally coin with the nitrogen forming silicon nitrid, for instance oi the formula con nu id formedflihe temperature is owered to aooui 900 ceutip nule and a mixture oi" chloride on sodium and potassium is added as a flux, into which the ali'uniniuin sinks to the bottom and melts togetlvr while the uitrid remains suspended in the slag or flux. If it is found that the alun'iiniuiu still contalus silicon and it is desired to obtain it. in a pure state the above l'lc rrihed treatment is repeated. The silicon nilrid then separated from the flux, in which it is suspended, either by lixiviatiug the chlorids and then filtering the obtained solution or by Volatiliziug the chlorids. The iluxing materials may of course be rccoveird and repeatedly employed. ii the aluminiiun silicate our plorcd in producing the aluminium siliron alloy is not quite pure or it the nitrogen treatment is not carried very tar, the resulting-aluminium will contain a quantity of iron and silicon as-inipuritics. To be obtained in quite a pure state the aluminium may in this case be subjected to a distilling process (optionally a tractional distillation or alloy of a metal and silicon to a temperature sufficient to react on nitrogen andv introducing a current of nitrogen in contact therewith, said compound being liquid at the temperature at Which the reaction takes place.
2. The process of manufacturing silicon nitrid which comprises heating a compound or alloy of a metal and silicon that becomes liquid at the reacting temperature of nitrogen and silicon, and conducting nitrogen in contact Withsaid liquid compound or alloy and evaporating the metal.
3. The process of manufacturing silicon nitrid which comprises conducting heated nitrogen into-contact With a melt of a compound or alloy of a metal and silicon.
4. The process of manufacturing silicon nitrid which comprises conducting nitrogen into contact with a melt of aluminium silicid and distilling the aluminium therefrom.
5. The process of manufacturing silicon nitrid which comprises conducting heated nitrogen into contact With a melt of aluminium silicid and distilling the aluminium therefrom.
In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing Witnesses.
