NOVEL PROCESS AND PRODUCT |
摘要 |
A process for manufacturing a compound in powder form, wherein said compound is the reaction product of (i) at least one metal and/or metalloid, and (ii) at least one further element that is more electronegative than the metal and/or metalloid, which process includes steps of: mixing at least one oxide of said at least one metal and/or metalloid with a reducing agent including Ca or Mg granules or powder, and/or calcium hydride or magnesium hydride in granule or powder form, to form a mixture; exposing the mixture to a source of said at least one further element; maintaining said mixture under a H2 atmosphere at a temperature of from 950° C. to 1500° C. for 1-10 hours; and, recovering said compound in powder form; wherein said at least one further element is selected from carbon, nitrogen, boron, silicon and mixtures thereof. A compound in powder form obtainable by such a process. |

1. A process for manufacturing a compound in powder form, wherein said compound is the reaction product of (i) at least one metal and/or metalloid, and (ii) at least one further element that is more electronegative than the or each said metal and/or metalloid, which process comprises the steps of:
a. mixing at least one oxide of said at least one metal and/or metalloid with a reducing agent to form a mixture, wherein the reducing agent comprises Ca, Mg, calcium hydride, magnesium hydride or a mixture thereof and is provided in the form of granules or a powder; b. contacting the mixture with a source of said at least one further element; c. maintaining said mixture under a H2 atmosphere at a temperature of from 950° C. to 1500° C. from 1 to 10 hours; and d. recovering said compound in powder form; wherein said at least one further element is selected from carbon, nitrogen, boron, silicon and mixtures thereof. |
