Fireproof high-temperature-resistant transparent glass and preparation method thereof

The invention relates to the field of fireproof glass, in particular to fireproof high-temperature-resistant transparent glass and a preparation method thereof. The glass is prepared from the following raw materials in parts by weight: 62-75 parts of SiO2, 5-15 parts of B2O5, 2-10 parts of Al2O3, 0.2-1.4 parts of Fe2O3, 3-17 parts of R2O and 5-14 parts of MO. According to the fireproof high-temperature-resistant transparent glass and the preparation method thereof, the defects that existing glass is poor in fire resistance and limited in protection function are overcome; the prepared glass hasexcellent fire resistance, and the thermal expansion softening temperature of the glass reaches 600 DEG C or above; and the glass is uniform in appearance, free of defects such as bubbles, stripes and crystallization, high in wear resistance and good in application prospects. 本发明涉及防火玻璃领域，尤其涉及一种防火耐高温的透明玻璃及其制备方法。按照重量份计，其原料包括：SiO2 62-75份，B2O5 5-15份，Al2O3 2-10份，Fe2O3 0.2-1.4份，R2O 3-17份，MO 5-14份。本发明通过提供一种防火耐高温的透明玻璃及其制备方法，解决了现
