Title: Synthesis of boron carbonitride
Inventor: SATO TADAO
IPC: C01B21/082
Filed: 1992-01-20
Abstract: PURPOSE:To provide a process capable of easily synthesizing boron carbonitride. CONSTITUTION:Boron carbonitride is synthesized by the thermal decomposition of an organic compound containing nitrogen and boron at the same time. Examples of the organic compound are organic borane, its derivative, organic borane nitride and its derivative. For example, boron carbonitride is formed on a substrate by heating a substrate 5 placed in a furnace having controllable atmosphere and introducing a raw material gas 7 composed of the organic compound into the furnace using a carrier gas such as nitrogen. Since this process is devoid of a raw material mixing step in contrast to conventional process, uniform boron carbonitride can be synthesized with an extremely simple operation.

Title: Desulfurization method from molten steel
Inventor: NISHI TAKAYUKI
IPC: C21C7/04
Filed: 1993-02-18
Abstract: PURPOSE:To effectively desulfurize a molten steel pipe by bringing CaO-contg refractories into contact with slag contg. CaO to make S in the molten steel absorbed into this slag. CONSTITUTION:The slag contg. the CaO is formed on the molten steel. The refractories consisting of the CaO as a main component is brought into contact with this slag. As a result, the S in the molten steel is effectively absorbed into the slag in which the CaO is maintained at high activity. The effect is higher if the calcium treatment in the molten steel is executed to make the S in the molten steel as sulfide adsorbed on the CaO. The desulfurization is accelerated by heating or stirring the slag via the CaO-contg. refractories at need. The CaO-contg. refractories are thereafter taken out of the slag, by which the adsorbed sulfide is removed outside the system and resulfurization is prevented.
