Inorganic anion exchanger with yttrium compound and resin composition for sealing electronic parts using the same

摘要

An object of the present invention is to provide a new inorganic anion exchanger that is environmentally friendly and has high performance. The present invention is an inorganic anion exchanger represented by the following formula (1). Y2Ox (OH) y (NO3) z.nH2O (1) (x, y, and z in formula (1) are 0 or a positive number, 2x + y + z = 6, and n is 0 or a positive number. In addition, the present invention provides a resin composition for encapsulating electronic components, a resin for encapsulating electronic components, and an electronic component using the inorganic anion exchanger represented by the above formula (1). Furthermore, the present invention provides varnishes, adhesives, pastes, and products containing these using the inorganic anion exchanger.
