We propose an investigation of the properties of apparent silicate emission features in the IR spectra of ultra compact HII regions. With SWS observations for the first time indications of such features towards HII region were seen. The relation of this material to the HII region is not at all clear. The proposed observations aim to significantly improve the signal to noise for these features, allowing a more detailed study of their properties and relation with the HII regions.
