Hello, I'm Materialscientist. I wanted to let you know that I removed an external link you added to the page Silicon nitride, because to me it seemed inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page, or take a look at our guidelines about links. Thanks, Materialscientist (talk) 10:18, 6 August 2012 (UTC)

Please do not add inappropriate external links to Wikipedia. Wikipedia is not a collection of links, nor should it be used for advertising or promotion. Inappropriate links include, but are not limited to, links to personal websites, links to websites with which you are affiliated (whether as a link in article text, or a citation in an article), and links that attract visitors to a website or promote a product. See the external links guideline and spam guideline for further explanations. Because Wikipedia uses the nofollow attribute value, its external links are disregarded by most search engines. If you feel the link should be added to the page, please discuss it on the associated talk page rather than re-adding it. Thank you. Deli nk (talk) 11:09, 6 October 2014 (UTC)
