Technology Overview

Transparent ceramics are highly durable optical materials, which can be utilized in extreme conditions that glass is unable to resist:

  • Their unique visible and infrared transmission can be preserved at high temperatures, above 1200°C.
  • They are chemically more stable than glass in highly corrosive conditions.
  • They exhibit more than 3X hardness and over 5X fracture strength in comparison to glass.

Transparent ceramics are commonly utilized in defense industry, as armor material thanks to their outstanding mechanical and optical properties. They can provide the same ballistic strength with conventional armors, by more than 60% reduced weight. MagSpin developed an economic powder processing technology and made it possible to apply these highly durable materials to non-military applications. What we do is not simply marketing the material by just matching the optical and mechanical properties with the intended application area. We provide specific solutions and innovative designs for particular applications, such as phones, watches and wearable technologies.

The table below provides the comparison of MagSpin with traditional glass, tempered glass and sapphire. Tempered glass is the most common material used in phone screens, whereas sapphire is utilized in watch screens. Hardness value of MagSpin is 3X times higher than plain glass and 2.5X higher than tempered glass. Thanks to its hardness, it is almost impossible to scratch MagSpin in daily use. Even though hardness of MagSpin is slightly below than that of sapphire, it has lower manufacturing costs. Moreover, it is possible to embed a calligraphy or graphic design in MagSpin. 

here will be a table


MagSpin is a ceramic material. It is produced by powder processing methods as the other ceramics. Different from opaque ceramics, transparent ceramics have hardly any porosity (<0.01%). Every stage of MagSpin production is inspected precisely, in order to approximate the theoretical density and to prevent any possible defects in the body, which will otherwise result in decreased optical transmission or optical homogeneity. A defect free body that allows high optical transmission and a controlled microstructure also results in superior mechanical properties. 


MagSpin has an optical transmission of 85% in the visible region. This value, which is pretty close to the theoretical transmission of the material, is consistent among the whole body. High and homogeneous optical transmission of MagSpin provides a more clear and sharper vision than glass.


Quasistatic tests were utilized for the mechanical characterization of MagSpin.  Hardness is one of the most important mechanical properties indicating resistance to scratch. Vickers hardness of MagSpin was measured as 1530 HV/10 (14-15 GPa).


Toughness value, which is associated with impact resistance, was also measured by indentation method. MagSpin produces diverse microstructure designs, varying according to specific applications. For example, the product introduced as phone screen is reinforced at the sides and the corners, where it is the most vulnerable to impact and damage during impact. Therefore toughness of MagSpin presents regional differences in certain products. Toughness value is 1.7 MPa.m1/2in transparent areas, whereas 3.5 MPa.m1/2in reinforced regions.
