Glass systems

  • Porous Vycor glasses (sodium borosilicate glasses)
  • Modified Vycor glasses (e.g. with iron)
  • Bioglass 45S5 (calcium phosphate silicate glasses)
  • Modified organic glasses (e.g. with strontium)
  • Bioglass ceramics (e.g. aluminosilicate glass ceramics containing fluorine and magnesium)
