Provided are a core material for a vacuum insulation panel including porous aluminosilicate, and a vacuum insulation panel provided with the same. The core material for the vacuum insulation panel according to the present disclosure has superior long-term durability and improved gas adsorption ability (particularly, superior water absorption ability) while requiring a low raw material cost. The vacuum insulation panel including the core material may exhibit more improved insulation performance by minimizing a reduction in the vacuum degree without an additional getter or absorbent.

A composition for packaging an electronic device comprises a matrix and an adsorption material having a water vapor adsorption capability, and the adsorption material includes attapulgite and/or zeolite. By adding attapulgite and/or zeolite which have an adsorption effect to modify the formulation of the frit, the compositions for packaging an electronic device can effectively reduce the influence of water vapor on the electronic device, thereby effectively extending the lifetime of the packaged electronic device.

The aluminum silicate of the invention has: an element ratio of Si and Al, represented by Si/Al, of from 0.3 to 1.0 by molar ratio; a peak at approximately 3 ppm in a .sup.27Al-NMR spectrum; peak A at approximately −78 ppm and peak B at approximately −85 ppm in a .sup.29Si-NMR spectrum; and a peak at approximately 2θ=26.9° and a peak at approximately 2θ=40.3° in a powder X-ray diffraction spectrum. The aluminum silicate has an area ratio of peak B with respect to peak A of from 2.0 to 9.0, or does not include a tubular substance having a length of 50 nm or more as observed in a transmission electron microscope (TEM) photograph of the aluminum silicate taken at a magnification of 100,000. The aluminum silicate is produced by a method comprising: subjecting a reaction product of a silicate ion solution and an aluminum ion solution to desalting and solid separation; subjecting a resultant to a thermal treatment in an aqueous medium in the presence of an acid under concentration conditions in an aqueous medium such that a silicon atom concentration is 100 mmol/L or more and an aluminum atom concentration is 100 mmol/L or more; and subjecting a resultant to further desalting and solid separation.

An adsorbent for halogenated anaesthetics includes: an inorganic material; and an organic material providing a framework for the inorganic material. The inorganic material may be chromium and the organic material may be terephthalic acid. The adsorbent may be formed or configured such that the adsorbent includes coordinatively unsaturated sites or such that the inorganic material may form octahedral structures. The adsorbent is formed or configured to be substantially regenerated at approximately room temperature and to provide selectivity for sevofluorane in water vapor of approximately 1.0. A method of producing an adsorbent includes: selecting an appropriate chemical containing an inorganic material; selecting an organic material to provide a framework for the inorganic material; dissolving the base chemical in water; mixing the organic material with the dissolved base chemical; heating the mixture; filtering the mixture to remove excess organic material; and drying the filtrate.
