At present, the highest usage rate of building decoration stone is quartz stone. The quartz stone is stirred by vacuum high pressure and high vibration by 93% quartz crystal and 7% resin and other binders. It belongs to artificial ston, also known as synthetic stone. Quartz stone has a smooth surface, compact and non-porous, and its color is comparable to natural stone. At the same time, it has certain toughness, no volatile gas, no toxicity, no radiation, and no use of color difference.

Quartz stone is a perfect combination of natural beauty and high technology. The slab is die-casted by pressure above 50 tons. The hardness is not less than 6 grades of Mohs hardness and the density is 2.6g / cm3. Quartz stone has a water absorption rate of only 0.02% and is resistant to penetration. The surface is cured at a high temperature of 150 degrees, so it has a high temperature resistance function, and the quartz stone can withstand a high temperature of 300 degrees.

Speaking of quartz stone can withstand high temperature of 300 degrees, many people will have their own views, the relevant documents produced by quartz stone manufacturers to customers show that quartz stone can withstand 300 degrees of high temperature. However, in use, the plates are often cracked after contact with high-temperature objects. Due to the high hardness of the quartz stone plates, it is difficult to repair after the explosion, so everyone has certain doubts about the high temperature resistance of the quartz stone.

How many degrees of high temperature can quartz stone withstand? I still say more than 300 degrees, because the quartz stone plate is heated to 300 degrees as a whole without any change. Many people will ask why in life when quartz surface contact with a hot pot will cause a burst! Quartz stone is a brittle polymer material with certain thermal expansion and contraction characteristics. When the surface is partially heated, it cannot withstand the internal stress caused by thermal expansion and contraction and will burst.
