    摘要: A membrane for use in an X-ray mask composed of a compound comprising at least three kinds of elements of boron (B), silicon (Si) and nitrogen (N) in which the content of silicon in the compound is at least 15 atomic percent, but less than 100 atomic percent, and the atomic ratio of Si/(B+Si) in the compound is at least 0.2, but less than one. The membrane is synthesized from source gases including at least the foregoing three kinds of elements by chemical reaction under such conditions that the ratio of nitrogen to boron plus silicon is at least one in the source gases and thereby depositing a film of the compound onto a substrate. Since the membrane thus prepared has a high transmittance in the visible region and X-ray and their residual stress can be readily controlled by adjusting the conditions for the formation of the membrane, it is suitable for the preparation of X-ray masks.

    摘要: The specification discloses a polycrystalline boron nitride of high purity and high density consisting essentially of rhombohedral crystals in which the three-fold rotation axes, parallel to the c-axis in the notation of hexagonal crystal system, of the crystals have a preferred orientation. The polycrystalline rhombohedral boron nitride can be obtained as bulk or thin film articles with desired shapes by chemical vapor deposition including the steps of introducing a source gas of boron and a source gas into a reactor containing a heated substrate and depositing boron nitride onto the heated substrate, wherein a diffusion layer of the source gas of nitrogen and/or the carrier gas is formed around the substrate. The polycrystalline rhombohedral boron nitride such obtained is very useful in applications such as crucibles for melting semiconductors, various jigs for high temperature services, high-frequency insulator, microwave transmission window and source material of boron for semiconductor. Further, the boron nitride is also ideal as a starting material for high pressure phase cubic boron nitride.

    摘要: Boron nitride containing titanium nitride in an amount of 0.05 to 10 wt. % which is produced at a relatively low temperature, utilizing a chemical vapor deposition technique. In the deposition process, boron, titanium and nitrogen source gases are introduced into an evacuated reactor together with a carrier and/or diluent gas and contacted with a heated substrate previously mounted in the reactor, whereby boron nitride with titanium nitride is deposited onto the substrate. The deposit thus obtained has a high density, a significantly improved heat-shielding ability, a high degree of anisotropy with respect to thermal diffusivity and a high chemical stability. By using such anisotropic boron nitride with BN ceramics, very useful BN type composite ceramics can be produced.
