公司：graphite question 国家：** 联系人：** 地址： This is an inquiry message about graphite question in the 108th China Canton Fair. (这是一条买家关于"graphite question"的询盘信息，来自第108届中国广交会。)Inquiry Message (询盘信息) graphite question Dear Sir or Madam, I am a neuroscientist working with borosilicate glass. Without going into too much detail, I am trying to soften small rectangular capillaries while they are on a firm surface. My goal is to lay one on top of another and get them to fuse. It was suggested that I use graphite. I bought some woodless graphite pencils, used them to create a flat surface. When I try to heat the capillaries, the graphite begins to smoke before the glass gets soft. I know that glass blowers use graphite paddles to mold soft glass but that borosilicate softens at higher temperatures than other forms of glass. My questions are: Is there something different about the graphite in pencils or is it just that glass blowers use glasses that soften at lower temperatures then borosilicate (about 830 degrees C, 1500 degrees F)? Is there a form of graphite (or another material) that can tolerate these temperatures without the glass sticking to it? Thank you for any help you can give me James Celentano, M.D., Ph.D. Dept of Physiology and Pharmacology SUNY Downstate Brooklyn, NY Contact Info (联系信息) James Celentano 11203 Company: SUNY Downstate E-mail: jimc10@aol.com jimc10@aol.com 电话：** 传真： ** 邮箱：** 网址：** 采购本类产品及：** |
