ABSTRACT = {Magnesite-bonded wood wool panel (MWWP) is an inorganic-bonded panel product in which wood excelsior is
bonded with magnesite. Lowering the hygroscopicity is one of the key measures to improve the quality of the
panel. In this study, moisture absorption mechanism of MWWP and measures generally applied to lower its
hygroscopicity were reviewed. Three methods were then experimented to improve the dimensional stability of
the panel, including adjusting the molar ratio of raw materials, adding additives and optimizing the conditioning
process. The results showed that satisfying dimensional stability could be achieved when the molar ratio of MgO
to MgCl<sub>2</sub> was 5:1, the No.2 composite additive (aluminum powder + NH<sub>4</sub>H<sub>2</sub>PO<sub>4</sub> + ferric alum) was adopted and
a constant temperature and humidity treatment was applied in the first stage of conditioning.},
