A quartz tube furnace is an electric heating device extensively used in material research. For example, ceramic research, wafer sintering and annealing and powder baking. The length of the quartz tubes are different. For experiments in laboratories the size of tube is from 1" to 13". The temperature is controlled via a feedback from a thermocouple. The temperature controllers often allow the operator to program the heating, dwelling and cooling rates. ==Fused Quartz Tube== * The commonly used quartz tubes are made of 99.9% SiO2. * The max constant working temperature is 1200 °C * Thermo-conductivity: 1.4 W/m × °C * Thermo-expansion: 5.5 × 10−6/°C * Flexural Strength: 48 MPa 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Quartz tube furnace」の詳細全文を読む スポンサード リンク
