In January 2015，a big fire happened in one of Russia’s largest university’s libraries.It burned up more than 1 million historical books and it was described by some media as a “cultural_Chernobyl(切尔诺贝利)”．

Thanks to a new fire－resistant(耐火的) paper，such accident can be avoid in the near future.Zhu Yingjie，a researcher from Shanghai Institute(研究所) and his team have developed a set of methods to produce paper with a new material，hydroxyapatite(羟磷灰石)，which was found in tooth and bone.It is resistant to both fire and water.

“Traditionally，paper is made of plant fibers，which are easily destroyed by water.The research in the past attempted to produce water－resistant and fire－resistant paper.However，they found it was difficult to achieve the goal at the same time，”Zhu said.

In 2013，a student of Zhu was dealing with hydroxyapatite.While he wanted to filter(过滤) out the water and continue the experiment，he found a film appeared on the filter paper，instead of getting hydroxyapatite powder(粉末)．The discovery inspired Zhu.He did more experiments to improve the material.

“Traditional papermaking needs lots of woods and damages the environment.Hydroxyapatite is a perfect material for paper，”Zhu said.

At present，Zhu and his team are making effort to improve the new material.Soon this kind of paper will be put into production.It is sure to make a big and deep difference to our life and the environment.
