Abstract
The glass contains a Ti component in a glass composition, in which a Ti3+ ion content is 80 ppm or less.
Claims15
1:
- A glass comprising a Ti component in a glass composition, wherein a Ti3+ ion content is 80 ppm or less.
2:
- The glass according to claim 1, wherein the Ti component comprises TiO2 in an amount of 0.1 mass % or greater.
3:
- The glass according to claim 1, further comprising an Fe component.
4:
- The glass according to claim 3, comprising the Fe component in an amount of 10 ppm or greater as calculated as Fe2O3.
5:
- The glass according to claim 1, comprising from 30 to 80 mass % of SiO2, from 0 to 30 mass % of Al2O3, from 0 to 30 mass % of B2O3, from 0 to 25 mass % of CaO, from 0 to 30 mass % of Na2O, from 0 to 30 mass % of K2O, from 0 to 10 mass % of Li2O, from 0.1 to 15 mass % of TiO2, from 0 to 20 mass % of Nb2O5, from 0 to 20 mass % of WO3, and from 0 to 10 mass % of F.

10:
- A resin composition comprising a curable resin and the glass according to claim 1.
11:
- The resin composition according to claim 10, comprising from 1 to 70 vol % of the glass.
12:
- The resin composition according to claim 10, which is for dental use.
13:
- A molded body comprising a cured product of the resin composition according to claim 10.
14:
- A manufacturing method of a molded body, the manufacturing method comprising curing a resin composition by irradiating a light beam to the resin composition, wherein the resin composition is the resin composition according to claim 10.
15:
- A manufacturing method of a molded body, the method comprising:
- forming a cured product layer by selectively irradiating a light beam to a liquid layer made of a resin composition, the cured product layer having a predetermined pattern;
- after forming a new liquid layer on the cured product layer, forming a new cured product layer by irradiating the light beam to the new liquid layer, the new cured product layer having a predetermined pattern continuous with the cured product layer;
- and
- repeating stacking of the cured product layers until a predetermined molded body is produced,
- wherein the resin composition is the resin composition according to claim 10.
