Yes, you can use Angular Material with Ionic. In fact, Ionic has built-in support for Angular Material.

To use Angular Material with Ionic, you need to install the
@angular/materialpackage and its dependencies in your project:
npm install @angular/material @angular/cdk @angular/animations
npm install @angular/material @angular/cdk @angular/animations
Then, you can import and use Angular Material components in your Ionic app. For example, you can import the MatButtonModule and use the mat-button directive in your template:
import { MatButtonModule } from '@angular/material/button';
@NgModule({
declarations: [
// ...
],
imports: [
// ...
MatButtonModule
],
bootstrap: [AppComponent]
})
export class AppModule { }
And in your template:
<button mat-button>My Button</button>
