摘要： PROBLEM TO BE SOLVED: To provide an inexpensive forsterite substrate which satisfies the peeling test of the marks formed on the substrate by laser irradiation and has a clear contrast with the substrate surface to be easily discriminable and high reliability of the airtightness.
SOLUTION: The raw material composition of the forsterite contains a calcined mixture of magnesia and silica in a molar ratio of 2:1, a sintering aid and an inorganic colorant turning black on sintering. The forsterite substrate is obtained by adding water, a binder and a plasticizer to the raw material composition, pulverizing the mixture to obtain slurry, drying and granulating the slurry to obtain granules and pressure-molding and sintering the granules. The sintering aid contained in the raw material composition of the forsterite comprises calcia, alumina and barium oxide. The barium oxide content is 5-30 wt.%. The inorganic colorant is one species element of manganese oxide and contained in an amount of 3-20 wt.%.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive forsterite substrate having high airtightness reliability in which a mark formed on the substrate itself by irradiation with laser has clear contrast with the surface of the substrate and is easily discriminated.
SOLUTION: The forsterite substrate is obtained by adding water, a binder and a plasticizer into a forsterite raw material composition obtained by calcining a mixture (2MgO SiO
2 ) having a ratio of magnesia to silica by mol of 2:1 then mixing a sintering agent and an inorganic coloring agent to develop a black color by sintering into the calcined mixture, drying and granulating the mixed slurry while pulverizing to form a granulated body and press forming and firing the granulated body. The inorganic coloring agent contained in the forsterite raw material composition comprises a simple substance of one kind of manganese oxide. In the forsterite substrate, it is preferable that the content of the inorganic coloring agent in the forsterite raw material composition is 3-20 wt.%.
