| abstract | The present invention relates to a sealing material containing glass powder and ceramic powder, which is suitable for laser sealing of low thermal expansion substrates such as alumina substrates and glass substrates, and can contribute to reduction in height and size of an airtight package. Provide ceramic powder that exhibits negative expansion even when the particle size is small. A ceramic in which β-eucryptite or β-quartz solid solution is precipitated as a main crystal phase, an average particle diameter D 50 is 20 μm or less, and a thermal expansion coefficient at 30 to 300 ° C. is negative. Powder. Ceramic powder containing Li 2 O: 16 to 30%, Al 2 O 3 : 10 to 35%, and SiO 2 : 30 to 68% in terms of mol% as a composition. Ceramic powder, wherein the powder is substantially free of glass phase. A sealing material comprising the ceramic powder and glass powder and using laser sealing. [Selection] Figure 2 |
