Question

For Gorilla glass, Xensation, Sapphire glass, and Dragontrail glass, how they are made and processed, their hardness, strength, and cost. In metric please.

Answer 1

Gorilla glass : is manufactured by a typical ion-exchange technique, alos known as the fusion method. Wherein, the material required for glass (aluminosilicate) are mixed together, melted at very high temperature and blended together. The ion as sodium gets replaced with larger potassium ions which induces extra stability and toughness to the material. They are considered to be very hard and are mostly used for manufacturer of mobile screens. The hardness value on the vickers scale is about 622-701 Kg/mm^2. On an average the cost of gorilla glass is somewhere around $0.07/per squeare cm.

Sapphire glass : As the name suggests are blue in color used in the manufacturer of glass screens. They are manufactured from alumina at very high temperature and pressure conditions wherein the Al2O3 or the sapphire slowly crystallizes out over a period of several days. They are known to resists stress to a great extent. Also used in the manufacture of mobile screens and an alternative to gorilla glass. This however costs much more high than gorilla glass with an average cost around $0.7 per square cm.

Dragontrail glass : manufactured by a japanese company, by their patented float technology. Aluminosilicate is the main material and manufacturing an dprocessing is done under highly regulated temperature and pressure conditions. the process makes they extremly tough and resistant to thermal changes. The hardness measured on vickers scale ranges around 593-673 Kg/mm^2. The average cost of the material is about $1-2 peer square cm.
