A method of manufacturing an aqueous solution of biocompounds containing peptide as a major component and a hydroxyapatite containing minerals and being useful an inorganic or organic composite material from tissue in an electrolytic cell by performing the electrolysis of an aqueous solution of the tissue and by taking advantage of an electrode reaction using suitable electrodes. In this case, a DC current is passed between the electrodes in the aqueous solution, thereby dissolving and crystallizing the tissue components. After unreacted matters are removed, the resultant mixed solution is separated into solid matters and a liquid. The aqueous solution of biocompounds is obtained from the filtrate, and the hydroxyapatite is obtained from the recrystallized solid matters.

Method of manufacturing hydroxyapatite and aqueous solution of

A silicon carbide coated carbon matrix/carbon fiber composite material is provided. The carbon composite base material, coated with silicon carbide, comprises a siliconized layer and a non-siliconized layer. The siliconized layer comprises silicon carbide matrix and non-siliconized carbon fibers. The siliconized layer also has a non-planar interface with a series of elongated protrusions penetrating into the surface the of non-siliconized layer. A gas-permeable intermediate coating formed on the carbon composite material can help produce such a siliconized layer.

Silicon carbide coated carbon composite material and method for making

A mirror for SOR includes a base (1) made of a heat resistant ceramic material having a surface, a first SiC coating (2, 3) formed on the surface of the base (1), which has a first smoothed surface, and a second SiC coating (4, 5) formed on the first smoothed surface of the first SiC coating (2, 3), which has a second smoothed surface. A third SiC coating can be formed on the smoothed surface of the second SiC coating (4).
