There is no scientific name per se for a rice hull.

However, according to Wikipedia:

"To protect the seed during the growing season, the hull is made of hard materials, including opaline silica and lignin.... The very high content in amorphous silica of the hulls confer to them and to their ash (SiO2 ~ 20 wt.%) after combustion very valuable properties."
