    • The present invention relates to a glass filler material with an average particle size of 0.1 - 20 µm. It further relates to a method for producing a glass filler material. The glass filler material comprises 65 - 99.95 mol% silicon dioxide (SiO 2 ), 0 - 15 mol% aluminum and/or boron oxide (Al 2 O 3 , B 2 O 3 ), 0 - 30 mol % zirconium and/or titanium and/or hafnium oxide (ZrO 2 , TiO 2 , HfO 2 ), Y 2 O 3 and/or Sc 2 O 3 and/or La 2 O 3 and/or CeO 2 and/or other lanthanidoxides, 0.05 - 4 mol% alkali metal oxides (Na 2 O, Li 2 O, K 2 O, Rb 2 O, Cs 2 O), 0 - 25 mol% earth alkali metal oxides (MgO, CaO, SrO, BaO).
      The glass filler material shows a low concentration of alkali ions and is used for composites with cationically curing properties and for dental composites and dental restoration materials.

    • A small-sized reactor having practical utility in light of a bonding force, ease in observation, exemption from impurities and high resistance against pressure, is provided. In bonding a plural number of inorganic transparent substrates (11) to (13) to form a small-sized reactor, surfaces for bonding (16) to (19) of the inorganic transparent substrates (11) to (13), bonded on contact to one another, are initially polished and planarized. A part of the surface of each of the surfaces for bonding is then machined. The surfaces for bonding (16) to (19) are then hydrophilicity enhanced and washed with pure water. A film of pure water is swung off and removed by a centrifugal force. The resultant product is then heated with the surfaces for bonding in contact with one another. The surfaces for bonding, in contact with one another, may be bonded together by chemical bonding via oxygen to form small-sized reactors (1), (2) in which the inorganic transparent substrates (11) to (13) are bonded together strongly. The reactor is transparent and hence an inner reaction may be observed. Moreover, the reactor is rigid and hence is high in resistance against pressure. Since no adhesive is used, there is no fear of dissolution of impurities.
    • 提供了一种具有粘合力,易于观察,免除杂质和高耐压性的实用性的小型反应器。 在将多个无机透明基板(11)〜(13)接合以形成小型反应器时,在无接触的无机透明基板(11)〜(13)上粘接(16)〜(19)的表面 彼此之间,最初被抛光和平坦化。 然后对每个用于粘合的表面的一部分表面进行加工。 然后将粘合(16)至(19)的表面亲水化并用纯水洗涤。 通过离心力将纯净的水膜摆脱并除去。 然后将所得产物与表面加热以进行粘合以彼此接触。 用于接合的表面可以通过氧气进行化学键合而结合在一起形成小型反应器(1),(2)其中无机透明基板(11)至(13)牢固地结合在一起 。 反应器是透明的,因此可以观察到内部反应。 此外,反应器是刚性的并且因此具有高的耐压性。 由于不使用粘合剂,所以不用担心杂质溶解。
