Tīmeklis2010. gada 23. marts · The melting point of most solder is in the region of 188°C (370°F) and the iron tip temperature is typically 330°C to 350°C (626°F to 662°F). Soldering Basics: Although tip temperature is not the key element in soldering you should always start at the lowest temperature possible. TīmeklisThree single crystals of LaB6, prepared from aluminium melts with different [B] [La] ratios, were investigated using X-ray diffractometry. Final agreement indices were 1.36%, 1.10% and 1.15%. Vacancies at the boron position were indicated, although not conclusively established, for all three crystals. The thermal vibrations of lanthanum …
