Features：
1. High refractory properties: Fused quartz tiles can withstand extremely high temperatures, often operating stably at temperatures above 1600°C.
2. Low coefficient of thermal expansion: Due to their low thermal expansion properties, fused quartz tiles deform very little when the temperature changes, which makes them more stable at high
temperatures.
3. Excellent chemical stability: It has high corrosion resistance to most acidic and alkaline substances, suitable for many chemical environments.
4. Low thermal conductivity: Its low thermal conductivity means that they insulate well, helping to retain heat and improve energy efficiency.
5. Excellent thermal shock resistance: It can withstand rapid temperature changes without cracking or damage, which is particularly important for certain operating conditions.
Application:
1. Fused silica bricks are widely used in kilns under various extreme conditions due to their excellent high temperature resistance and corrosion resistance.
2. Glass kilns: Fused quartz bricks are often used in the glass production process because their high temperature resistance and chemical stability can withstand the high temperature and
chemical erosion of molten glass.
3. Aluminum smelting furnace: In the aluminum smelting process, fused quartz bricks can resist high temperatures and corrosion of molten aluminum.
4. Steel smelting furnace: In some high-temperature steel smelting processes, fused quartz bricks are used in furnace linings and other important parts due to their high temperature resistance and chemical stability.
5. Ceramic kilns: Kilns used in high-temperature ceramic firing processes, the low thermal expansion and high refractoriness of fused quartz bricks can ensure the stable operation of the kiln.
